JavaScript By Example - Functions

The global parseInt function makes it easy to convert numbers to base 10 from any other number base.

This function converts text strings to floating point numbers making it easy to define very large and very small numbers.

This function provides a means of testing whether JavaScript considers a value to be capable of processing as a number or not. It returns true if the value is not a number.

This function tests both that the value is a number and also that the number isn't too big for processing.

These functions 'escape' those characters that could lead to content being misinterpreted and help keep it separate from the surrounding content.

This function allows you to specify a delay before running a function.

This function looks the same as setTimeout but instead of running the function once, it runs it over and over with the specified interval in between.
