Learn how to apply JavaScript to real-world problems.

Zero to Hero in Front-end Development with React

In this module, we’ll dissect every part of JavaScript’s basic concepts. We’ll start by running through JavaScript fundamentals, such as arrays, types, variables, and conditional statements. Additionally, we’ll learn about regular expressions and DOM manipulation. Once we finish this module, we’ll have a deeper knowledge of the language and be ready to tackle some projects.

JavaScript: A Deep Dive

## Background

In programming, we frequently *parse* or make *queries* over strings. Pattern matchings become tedious when writing string manipulation or *iteration* code. Moreover, it is not always best to write loops to *index* and *iterate* strings for manipulation. The solution to these issues? **Regular expressions**.

## Introduction

**Regular expressions** are *expressions* containing a sequence of characters to invoke a *sequence matching* or *pattern matching* of strings. They usually carry out “search and replace” actions. These are sometimes called rational expressions or **RegEx** for short. RegExes are available in most programming languages including JavaScript.
