Type Conversion and Type Coercion in JavaScript

Type Conversion :

Conversion using built-in Functions by Developers
Example : String() , Number() and Boolean().

String()
Number()
Boolean()

Type Coercion:

The process of automatic or implicit conversion of values from one data type to another.

Since JavaScript is a weakly-typed language, in some scenarios Conversions are done by compiler automatically.
Example : 1== null

Rules :

String on any side of operand returns converts into string before operation.
No String on either side with all primitives, it converts into Number before operation.
Array, Objects are considered as string before conversion.
