Question

In javascript : is it legal ?

 var obj = [ id: '1', name: '' ]; 

type typeof(obj) return n/a

Answer 1

That is a syntax error in JavaScript. Probably it should be:

var obj = { id: '1', name: '' };

That’s an object literal. An array literal looks like this:

var arr = [ 1, 2, 3 ];

You can put objects inside of arrays too:

var objarr = [ { id: '1', name: '' }, { id: '2', name: 'example' } ];

An empty object looks like:

var emptyObj = {};

An empty array looks like:

var emptyArr = [];
