Description

In JavaScript, all functions are technically Function objects and provide users with an alternative way to encapsulate statements to perform more powerful and useful actions in a reusable piece of code. Regular expressions ease the task of validating data in JavaScript programs. This course will explore how to use Function objects and useful predefined functions that are part of the JavaScript language. It will also detail the regular expression support built into JavaScript that allows developers to perform pattern matching and validation of user-entered data. Specific topics covered will include Function objects, recursion, anonymous functions, predefined JavaScript functions, and pattern matching using regular expressions. This course is one of a series covering the fundamentals of the JavaScript language.
