How to Convert a String to a Number in JavaScript?

This means that the value of parseInt does not have to convert any numbers except for numeric strings, no matter how large or small the number may be. This can have drastic implications when you are dealing with large or small numbers and is particularly useful if you are saving a variable's value to a text file, where it can be retrieved at a later time.
