What is the difference between == and === in javascript?
Answer:
== operator tests for abstract equality. The operator does the necessary type conversion before doing the equality comparison.
This operator checks for value.
Example:
100==”100″
The above condition returns true. The right-hand side string is converted to a number and then compared to 100.
- === operator tests for strict equality.
- No type of conversion happens with this operator.
- This operator checks for both value and type.
Example:
100===”100″
The above condition returns false. Here value is 100 and but their type is not the same. so it returns false.
