What does the != operator do?

The not-equal-to operator ( != ) returns true if the operands don't have the same value; otherwise, it returns false .

Why do we prefer === and !== Over == and != In JavaScript?

This is because the equality operator == does type coercion, meaning that the interpreter implicitly tries to convert the values before comparing. On the other hand, the identity operator === does not do type coercion, and thus does not convert the values when comparing.

Is == and === same in JavaScript?

The main difference between the == and === operator in javascript is that the == operator does the type conversion of the operands before comparison, whereas the === operator compares the values as well as the data types of the operands.

What is the meaning of == and === in JavaScript?

= is used for assigning values to a variable in JavaScript. == is used for comparison between two variables irrespective of the datatype of variable. === is used for comparision between two variables but this will check strict type, which means it will check datatype and compare two values.
