20,739,000 | split string only when two or more spaces occurs.
```
string="Talk Talk Walk Walk sell sell";

Expected Result after split:
```
string[0]='Talk Talk';

] | You can use the regular expression `/\s{2,}/`, which means that, if there are 2 or more white space characters, split the string there.
```
myString="Talk Talk Walk Walk sell sell";
console.log(myString.split(/\s{2,}/));
```
**Output**
```
[ 'Talk Talk', 'Walk Walk', 'sell sell' ]
``` | **Try this simple way:**
```
var x = str.split(" +");

] | If your CO detector were actually detecting CO, it would not chirp. It would sound a continuous, and very, VERY loud alarm you would definitely recognize.
The chirping is a universal (as far as I know) method for indicating that it's time to change the battery. This is true for CO and smoke detectors. | It's normal for gas and smoke detector batteries to indicate impending failure during the coolest part of the day. The chemical reaction that produces the electrical current is reduced by low temperatures.

Detector end of life is probably the second most common cause.

Having said that, if it's easy, and it should be, replace the battery. If it still chirps - at the same time every day- you can rule out battery. this is the first step.

I think the answers here are spot on but I'll just add on:
1. Some CO detectors, when set off, sounds like a BEEP-BEEP-BEEP then a pause and it continues with the series of beeps, etc. They're loud but not as loud as a commercial fire alarm in s... |
