Question

What are the recommendations to create new object in Javascript?

Answer 1

It is recommended to avoid creating new objects using new Object(). Instead you can initialize values based on it's type to create the objects.

1. Assign {} instead of new Object()
2. Assign "" instead of new String()
3. Assign 0 instead of new Number()
4. Assign false instead of new Boolean()
5. Assign [] instead of new Array()
6. Assign /()/ instead of new RegExp()
7. Assign function (){} instead of new Function()

You can define them as an example,

var v1 = {};
var v2 = "";
var v3 = 0;
var v4 = false;
var v5 = [];
var v6 = /()/;
var v7 = function () {};
