In JavaScript, we can use the Number.isInteger() method to check whether a given value is a number or not.

The Number.isInteger() method returns true if a given value is a number, otherwise it returns false.

Here is an example:

function isNumeric(value){   return Number.isInteger(value);}isNumeric(1222); // trueisNumeric('1222'); // falseisNumeric('booo'); // false

If the given value is Infinity or not a number it returns false.

isNumeric(Infinity) //  falseisNumeric(-Infinity) //  falseisNumeric(0) // true

Similarly, we can also use the isNan() function in JavaScript.

isNan(3); // falseisNan(4); // falseisNan('hi'); // true
