0 == ''

Question

Its true or false?????

Answer 1

In JavaScript
0 == "" returns true
0 === "" returns false

Answer 2

== , loose equality operator will perform type conversion when comparing it's operands.

in given example 0==''
The String '' is type casted to Number type. When an empty string is casted to Number it becomes 0.

You can verify:
console.log(Number(''))

Also as pointed out by KINGDX
=== which is strict equality operator will return false if both operands are of different types. There will be no type conversion for comparison.

Answer 3

ConsoleLog that to find out. 😃
