You might think of regular expressions as the holy grail of text processing, but are you sure you aren't just shoehorning them in where standard built-in solutions already exist and would work better? JavaScript itself provides programmers with excellent methods for text manipulation, and knowing how and when to use them will help you write more efficient and performant code. From extracting data from APIs to calculating word counts and everything in between, discover how to pick the right tool for the job and make the absolute most of it every single time.
Whether you're a beginner or an advanced programmer, this up-to-date guide will save you a ton of time when dealing with text. With Text Processing with JavaScript, you'll find a collection of tiny programs, each demonstrating a string manipulation approach in JavaScript. You'll also focus squarely on the practical aspects of text processing with JavaScript - that is, what each technique is designed to accomplish and how to use it in your program.
Most popular programming languages support regular expressions, and there’s a good reason for that: regular expressions are incredibly powerful at text processing. With regular expressions, you can greatly reduce the time and effort required for complex string parsing tasks that would otherwise take dozens of lines of code. But, as a JavaScript developer, you may not need to jump into writing regular expression patterns whenever you need to process texts. JavaScript already provides excellent built-in tools that meet many of your text manipulation needs. In this book, you’ll explore when and how to use each tool by working through real-world scenarios. You’ll learn the mechanics of JavaScript’s regex in detail via cookbook-style recipes for various text manipulation tasks.
Discover how to extract data from APIs and web pages, apply spelling corrections, convert and format currencies, and remove HTML tags from text. Learn to intersect tables, copy text to the clipboard, extract lists from text, and highlight sentences that contain a specific word. Find duplicate words and fix them automatically, modify a copy of an existing regex literal, match the beginning or end of a string, and remove all comments from JavaScript and HTML files with ease. Match non-ASCII words, calculate the word count of an article in any language, and more.
