How to use double equals (==) operator In Javascript
This operator checks for value equality but not type equality.
Example: In this example, we are checking the equality of the strings by using the double equals(==) operator.
const numStr = '42';
if (numStr == 42) {
console.log('The values are equal');
} else {
console.log('The values are not equal');
}
Output
The values are equal
