JS data type


We are having mainly two types of data types in Javascript which are as follows :-

  • Primitive Data Type
  • Non-Primitive Data Type

Mainly we declare our data types just by using var , although we are having different declaration also by which we can declare our data type, but we will be reading about them later

Syntax
