var obj = { field: 2 };

<p>and in the code:
<code>
do_something( obj.fiel ); // note: field spelt wrong
</code></p>
<p>ie The property is incorrectly typed. I want to detect these bugs as early as possible.</p>
<p>I wanted to seal the object, ie
<code>obj = Object.seal(obj);</code></p>
<p>But that only seems to prevent errors like <code>obj.fiel = 2;</code> and does not throw errors when the field is simply read.</p>
<p>Is there any way to lock the object down so any read access to missing properties is detected and thrown?</p>
<p>thanks,
Paul</p>
<p>EDIT: Further info about the situation</p>
<ol>
<li>Plain javascript, no compilers.</li>
<li>Libraries used by inexperienced programmers for math calc purposes. I want to limit their errors. I can spot a misspelt variable but they can't.</li>
<li>Want to detect as many errors as possible, as early as possible. ie at compile time (best), at runtime with thrown error as soon as wrong spelling encountered (ok), or when analysing results and finding incorrect calculation outputs (very very bad).</li>
<li>Unit tests are not really an option as the purpose of the math is to discover new knowledge, thus the answers to the math is often not known in advance. And again, inexperienced programmers so hard to teach them unit testing.</li>

4,604,065 | 4,604,066 | Any better alternatives for getting the digits of a number? (C++) | <p>I know that you can get the digits of a number using modulus and division. The following is how I've done it in the past: (Psuedocode so as to make students reading this do <em>some</em> work for their homework assignment):</p>
<pre><code>int pointer getDigits(int number)
initialize int pointer to array of some size
initialize int i to zero
while number is greater than zero
store result of number mod 10 in array at index i
divide number by 10 and store result in number
increment i
return int pointer
</code></pre>
<p>Anyway, I was wondering if there is a better, more efficient way to accomplish this task? If not, is there <em>any</em> alternative methods for this task, avoiding the use of strings? C-style or otherwise?</p>
<p>Thanks. I ask because I'm going to be wanting to do this in a personal project of mine, and I would like to do it as efficiently as possible. </p>
