JavaScript: When you need two ways to do it

Unsure what's the point. Is it bashing JS? It's pretty much the same everywhere. For instance I'm learning elixir and you have

1. Enum & list comprehensions 2. `error`, `throw`, `exit` . Try/catch, try/rescue 3. `import`, `require`, `use`

I mean there are subtle differences, just like with JavaScript. so..?

If anything, Javascript doesn't have the luxury to do a breaking change.
