babel-plugin-decomma

Transpiles comma expressions to normal expressions.

Usage no npm install needed!

<script type="module">
  import babelPluginDecomma from 'https://cdn.skypack.dev/babel-plugin-decomma';
</script>

Removes comma expressions.

Input:

const val = (0, a.func)();
const nested = (1, (2, (3, NaN)));
if ((0, b.bar)()) {
}

Output:

0;
const val = a.func();
1;
2;
3;
const nested = NaN;
0;
if (b.bar()) {
}

Currently no optimization is performed, like removing the constant values that are not assigned to anything. This is on the TODO list.
