javascript - Is there a big difference between reference and primitive types of boolean, number etc.? -

-

i rad, can create numbers as:

var num = 10;

and:

var num = new number(10);

may use first variation of declaration?

yes, use first 1 always, returns primitive value.

the second method looks returns primitive value doesn't. infact, returns object boxed primitive value.

to explain this, lets declare 2 variables:

var = 2; var b = new number(2);

the expression a == b return true since javascript coerces b primitive value of 2. however, expression a === b return false types different: a being primitive , b being object.
