How to Check If a String is an Integer in JavaScript
Greetings, in this JavaScript tutorial we shall be checking if a string is a valid integer. This validation will also allow for negative integers, for example -5 would be considered valid. 22 and 0 would also be considered valid. 2.2 and -4.20 would be invalid as they are not integers. This is great if you want to ensure your user inputs only an integer.
You can also remove the check for a - symbol if you only want the user to input a positive integer/whole number.
Thanks for watching this JavaScript integer validation tutorial.
