When checking string if its a number, there are a lot of ways you can check a string if its a number. You can use regex, isNaN() function, or a plus operator, or parseInt.

But the best function that we can use is a function called Number().

The Number() function converts the argument to a number representing the object’s value. If it fails to convert the value to a number, it returns NaN.

We can use it with strings also to check whether a given string is a number or not.

console.log(Number('195')) // 195
console.log(Number('boo')) // Nan
