How to check if the given value is an integer or not in JavaScript
There is a Number.isInteger() method in JavaScript which helps us to check the whether a given value is an integer or not.
Number.isInteger() method returns true whether a given value is number otherwise it returns false.
function isNumeric(value){
return Number.isInteger(value);
}
isNumeric(1222); // true
isNumeric('1222'); // false
isNumeric('booo'); // false
If the given value is Infinity or not a number returns false.
isNumeric(Infinity) // false
isNumeric(-Infinity) // false
isNumeric(0) // true
Happy coding…
