JavaScript Object

[Prathyusha G]

Hi,

My question is whether the JavaScript Object - Key beginning with number is allowed?

@Prathyusha G Tested this with a background script and key beginning with a number is allowed.

Here is the script you can run on your instance to verify.

var javaScriptObj = {123:456}
var javaScriptObj1 = {'123':'OneTwoThree'}
var javaScriptObj2 = {'123Number':'Number and letters'}
gs.print(javaScriptObj[123]);
gs.print(javaScriptObj1['123']);
gs.print(javaScriptObj2['123Number']);

Here is what ECMAScript specification says:

A property key is either a String or a Symbol. All Strings and Symbols, including the empty String, are valid as property keys.
