[3807.44 --> 3811.60] um you just you just play your part and then you have this great community resource spectacular |
[3811.60 --> 3818.16] yeah exactly yeah so what about learning so that's how you get technically started but what if i don't |
[3818.16 --> 3823.68] have any idea what type annotations are or i want to learn how to write them and where do i go for that |
[3824.48 --> 3828.16] so there's a there's a couple of resources on the website that you can use to get started |
[3828.72 --> 3834.16] um we've got some samples so if you if just staring at code is the easiest way for you to learn |
[3834.96 --> 3838.40] you can go and there's a sample section on the website and you look through that and there's |
[3838.40 --> 3845.60] each of them are fairly small um examples of using node or using jquery just enough to kind of |
[3846.32 --> 3854.32] get you started uh there's also a handbook uh the handbook tries in plain english as best as i've been |
[3854.32 --> 3862.16] able to write plain english uh to to walk you through the various features and the 1.0 uh the 1.0 language |
[3862.16 --> 3867.36] and we'll we'll be kind of revising that um here shortly to kind of pull it up to date with the |
[3867.36 --> 3873.52] later versions of language but if you read through that you there's tons of examples uh tons of plain |
[3873.52 --> 3879.76] text to kind of understand um and you know maybe to call it the spec if you are the kind of person |
[3879.76 --> 3884.32] that really likes to dig into the details there's the typescript spec and you can read that and |
[3884.32 --> 3891.12] really understand it in a deep deep level speaking of the spec i noticed that was in a pdf is that spec |
[3891.12 --> 3895.76] ever going to be open source on github or is it already open source and this is compiled from a |
[3895.76 --> 3902.80] repo or something it's it's it's well it's available in three different ways as a as a doc file as a pdf |
[3902.80 --> 3910.16] file and in markdown so it it's it's on there if you just go to the front page on our github site and |
[3910.16 --> 3915.20] then link there's a link to the language specification and that's a markdown a single markdown file so okay |
[3915.20 --> 3921.92] guys i'll leave that up then yeah so next up let's talk about the future a little bit um you have a |
[3921.92 --> 3928.16] roadmap on the website that you you told us about uh maybe kind of just verbalize the roadmap a little |
[3928.16 --> 3935.20] bit and tell us um where typefers at as far as i think we are at a 1.4 release and 1.5 is in alpha |
[3935.20 --> 3942.80] or beta and then kind of what you guys see you go into next sure so the the 1.5 release is going to |
[3942.80 --> 3948.64] close a lot of the gaps that we had in es6 compatibility i think after 1.5 there's only a |
[3948.64 --> 3956.08] couple of features left class expressions um generators that we'll need to add to to kind of |
[3956.08 --> 3962.24] finish up the es6 compatibility so that's that's kind of a a nice milestone for us to actually be |
[3962.24 --> 3968.40] able to say yes we are a superset of javascript and that superset is a superset of es6 um we're |
[3968.40 --> 3974.24] looking at es7 features andrews mentioned async away earlier that's going to be fun for kind of |
[3974.24 --> 3981.12] the promise programming uh style to be able to have nice clean uh async away code we've been |
[3981.12 --> 3987.76] talking more recently about things like jsx and exploring jsx support um there's a pull request |
[3987.76 --> 3993.52] now if people want to kind of hop on and help out and give us their feedback we would love that so um |
[3993.52 --> 4000.40] so definitely definitely do that and decorators is another one yeah so so um but basically we're |
[4000.40 --> 4008.24] like 1.4 is is is the version that's out there now 1.5 is is imminent you know within a month or or two |
[4008.24 --> 4016.32] um we plan to ship that 1.6 will be the one that that rounds out a few more of the missing features |
[4016.32 --> 4024.08] and then finally 2.0 will will be done with with es6 and and the es7 things that that we so far have |
[4024.64 --> 4028.88] have on our roadmap but then i'm sure by then we'll we'll have dreamt up some more work you know but so |
[4028.88 --> 4037.84] um it just it just keeps on coming it it seems i i know that we're talking now about doing something |
[4037.84 --> 4045.52] around uh module bundling also to make it easier to consume es6 modules in a browser environment which |
[4045.52 --> 4052.08] today requires you to use an external module loader and you know so there's like there's there's a ton of |
[4052.08 --> 4058.32] stuff we can do uh and we can of course always do more ide features and and and so so there's no |
[4058.32 --> 4064.32] shortage yeah exactly i mean one of the things with with the javascript committee um is that they're |
[4064.32 --> 4072.40] now on a one-year cadence so every year they're going to revise uh ecma script so es7 is next and |
[4072.40 --> 4077.36] es8 is the following year i mean we're going to be busy just keeping up and being a super set |
[4077.36 --> 4083.28] uh with a nice rich type system and tooling that that builds on top of that so is it fair to say |
[4083.28 --> 4087.20] the type system is pretty much done and now it's just going to be in maintenance mode and now it's |
[4087.20 --> 4091.20] just keeping up or is there additional things that you can do to make the type system better over time |
[4091.20 --> 4096.32] as well oh no there are definitely things we can do to make the type system better you can always make |
[4096.32 --> 4103.04] type systems better um i mean we were talking with the the flow guys about union types and they're like |
[4103.04 --> 4108.64] great if you have an if an if statement and then you check what the type is in that if statement you |
[4108.64 --> 4113.68] know in the body of the if what the type is and as we're brainstorming with them we're like oh that's |
[4113.68 --> 4118.64] that's a no-brainer let's throw that in there too um so as people do explorations i think the the |
[4118.64 --> 4122.64] type system is just as organic as such a javascript language it's going to grow and and kind of |
[4122.64 --> 4129.44] incorporate patterns and whatnot uh that we can yeah yeah we're sort of always on the lookout for |
[4129.44 --> 4136.32] you know why did i have to put a typecast here why did i have to have this annotation or you know |
[4136.32 --> 4141.20] could is there a way we get rid of that uh you know so so is there a way you could capture this |
[4141.84 --> 4148.00] this pattern or this idiom you know in the type system so so we could better you know sort of |
[4148.00 --> 4154.64] understand it without you having to annotate anything um so that that and that's going to be ongoing plus |
[4154.64 --> 4160.24] you know whenever a new feature is introduced in the language we have to sort of work out the type |
[4160.24 --> 4165.92] theory behind that feature right and and get that integrated into typescript so so there's always that |
[4165.92 --> 4174.00] angle to it as well we've got uh 1.5 it's an alfie just announced that about 20 days ago you got your |
[4174.00 --> 4179.84] roadmap which is i love your roadmap too by the way it's great that how it's linking out to issues that |
[4179.84 --> 4185.68] have commentary from you all in the community sort of feeding back into this i think it's a really |
[4185.68 --> 4191.84] great way to line out a a road not not just uh straight up text but when we're talking about the |
[4191.84 --> 4198.56] roadmap and future versions of typescript what do we let's have some fun and hypothesize uh each of you |
[4198.56 --> 4203.20] towards what the future of typescript might might be where would we be at in a year what we'll be |
[4203.20 --> 4210.40] talking about for typescript well i mean i i i'll be a little bit pedestrian i i still think we're |
[4210.40 --> 4216.88] going to be talking a lot about es6 and we're going to be talking a lot about modules because es6 isn't |
[4216.88 --> 4221.92] quite done when it comes to to to modules you know they've spec'd the language syntax but they haven't |
[4221.92 --> 4228.56] actually spec'd the underlying runtime loader semantics um and and so so there's still a whole |
[4228.56 --> 4235.60] bunch of gyrating going on in the community around that right now uh i think some of the new es7 |
[4235.60 --> 4241.92] features we're going to be looking at we're going to be looking at different uh development tools to |
[4241.92 --> 4250.40] integrate with uh maybe deeper integration with build systems and and sort of this whole the whole cycle of |
[4251.44 --> 4257.60] i edit something and now i click on my browser i want to see the result over there and and shortening |
[4257.60 --> 4263.76] that as much as possible right and making the compilation step as automatic and as and as and as |
[4263.76 --> 4269.84] ephemeral as possible right is is something that we're gonna that we're gonna keep iterating on um |
[4269.84 --> 4275.44] for sure um are there any particular uh adoptions of typescript that you're looking forward to like |
[4275.44 --> 4280.64] uh is there anyone out there that is a perfect candidate for it that if they were listening to the show |
[4280.64 --> 4285.92] right now you know they would you would put them on your radar essentially to say y'all should adopt |
[4285.92 --> 4294.72] typescript well i think you know anyone who has more than say 10 or 20 000 lines of javascript in |
[4294.72 --> 4301.20] their app really owe it to themselves to take a look at at this because it really is a time saver i i |
[4302.24 --> 4307.36] i i will say you know like like just you know the project that we work on daily which is the |
[4307.36 --> 4312.96] typescript compiler itself but it but in a sense it's just a large javascript app right it's a 50 000 |
[4312.96 --> 4318.88] line javascript app i shudder to think what it would be like to write that without types i i don't |
[4318.88 --> 4325.52] i can't even i mean i can't even imagine i mean because we refactor that so much right and that's |
[4325.52 --> 4330.72] what gives us our agility and the ability to keep up with all of these features and and these new |
[4330.72 --> 4335.28] things that are happening it's like that you can trust the system you can go okay well i'm gonna now |
[4335.28 --> 4339.60] i'm gonna refactor this class or this interface or this function into these two things and i'm gonna |
[4339.60 --> 4345.60] rename these properties and boom boom boom done and now i now i get all this time back that i can |
[4345.60 --> 4353.60] use to creatively think about the problem instead of doing the manual labor that it otherwise turns into |
[4353.60 --> 4361.20] right yeah and to me that is just like that's just bread and butter i mean you just gotta do that if you |
[4361.20 --> 4367.92] want to stay competitive you know so yeah we have a few closing questions i share with you all via email |
[4367.92 --> 4373.92] that uh we got several but we're only going to do two today um and the first uh we could take turns |
[4373.92 --> 4378.72] and we can start with you but who is your programming hero |
[4382.00 --> 4386.24] yeah jonathan and i were actually we're talking about that at lunch i i think you know if i have to |
[4386.24 --> 4391.92] think back on my career and who had the sort of biggest impact and then then launched me into this |
[4391.92 --> 4399.44] whole thing it's probably uh the inventor of pascal uh niklaus birt um who's uh i i i was fondly |
[4399.44 --> 4405.52] recounting and ben jonathan knows the book too his his book called uh algorithms but plus data structures |
[4405.52 --> 4412.24] equals programs um one of my favorite computing books i remember reading it cover to cover and |
[4412.24 --> 4418.88] understanding every word in there it just made so much sense it is so simple that's how i learned about |
[4418.88 --> 4424.24] hash tables which i i didn't know about when i first wrote the first version of turbo pascal |
[4425.12 --> 4429.84] and then i read about these things called hash tables i'm wow that what really and then i went |
