How to change Code Style on WebStorm/IDEA
<p>This is the code style used on my current JavaScript project:</p>

<pre><code>var obj = {
  a: 1
, b: 2
, c: 3
}

var arr = [
  'a1'
, 'a2'
, 'a3'
]

const w = 1
  , w2 = 2
  , w3 = 3
</code></pre>

<p>They say they are using <a href="https://docs.npmjs.com/misc/coding-style" rel="nofollow">npm's coding-style</a>.
And I'm trying to configure my <a href="https://www.jetbrains.com/webstorm/" rel="nofollow">WebStorm</a> IDE to use it, but I cannot find or create the correct configuration. WebStorm keeps fixing me all those commas.
E.g. this code:</p>

<pre><code>var obj = {
  a: 1
, b: 2
, c: 3
}
</code></pre>

<p>WebStorm transforms to this:</p>

<pre><code>var obj = {
  a: 1
  , b: 2
  , c: 3
}
</code></pre>

<p>Please help me to do it.
Thank you.</p>
