Is there a function in javascript similar to compact from php?

Question

I found compact function very useful (in php). Here is what it does:

$some_var = 'value';
$ar = compact('some_var');
//now $ar is array('some_var' => 'value') 

So it create array from variables which you specify, when key for elements is variable name. Is there any kind of function in javascript ?

Answer 1

You can use ES6/ES2015 Object initializer

Example:

let bar = 'bar', foo = 'foo', baz = 'baz'; // declare variables

let obj = {bar, foo, baz}; // use object initializer

console.log(obj);

{bar: 'bar', foo: 'foo', baz: 'baz'} // output

Beware of browsers compatibilities, you always can use Babel
