javascript check if number
//Updated dec 2020 // The first 2 Variations return a Boolean // They just work the opposite way around // IsInteger if (Number.isInteger(val)) { // It is indeed a number } // isNaN (is not a number) if (isNaN(val)) { // It is not a number } // Another option is typeof which return a string if (typeof(val) === 'number') { // Guess what, it's a bloody number! }
