This brief tutorial will show you two ways to convert JavaScript arrays to strings using the toString() and join() methods. What Are Arrays? An array is a data structure which holds multiple values. It’s like a numbered list – each item in the array has a value and a position (called the index). The indexes start counting at position 0, so the first item in an array is at index 0, the second at index 1 and so on. Converting Arrays to Strings in JavaScript There are many reasons you may wish … Read more

This quick tutorial will show you how to reverse a string in JavaScript. Strings are Array-Like Strings in JavaScript are considered array-like. A string is an ordered series of characters, so it can be considered as an array of characters. This makes it easy to convert a string to an array. We can then use any one of the methods available for reversing the array to reverse the string. This means you can use any of the methods we’ve previously outlined on reversing arrays on strings. … Read more

This quick tutorial will show you how to compare two or more strings in the JavaScript programming language – optionally ignoring case – with code examples. What are Strings? Strings are a series of characters. Each character has an ordered position in the string. A string can be of any length – from 0 (zero) characters to as many as you need until your computer runs out of memory. Strings are a type of variable. String type variables in JavaScript are variables that can hold a string … Read more

This tutorial will explain a few ways to remove the first or last character (or both!) from a string in the JavaScript programming language. This can be useful if you need to capitalize names or sentences or remove punctuation. Remove First/Last Character Using The substring() Method The JavaScript substring() method can be used to remove the first or last character from a string. You can find out more about the substring() and similar substr() methods here. The below code example shows how to remove the first, last, and both the first … Read more

JavaScript has two similar-looking methods for extracting substrings from strings – substr() and substring(). This article explains the difference. These two functions perform almost the same function and have almost the same name, and at a glance, even seem to have the same syntax – but they’re different! Here is the syntax for each function – side by side so that you can see the difference. A Quick Reminder about Indexes An index is the integer number representing the position of an item in a series. Indexes start counting at 0 – so the … Read more

This short article shows you how to capitalize the first letter in a string or all of the words in a string (title case) in the javascript programming language. Capitalizing the first letter in a string is useful if you’re capitalizing a single word or a whole sentence which you wish to display in a grammatically correct manner. Converting a string to title case – that’s where every word is capitalized in a string with multiple words – is useful for formatting text for use in an article … Read more

Here are some easy-to-understand methods for converting strings to date objects in the JavaScript Programming language. Looking to compare dates in JavaScript? Find out how here. The Hard Way – Using Vanilla JavaScript JavaScript contains built-in functions for parsing a date from a string – but it’s severely limited. So here it is in action: var myString = ’01 Jan 1970 00:00:00 GMT’; var myDate = new Date(Date.parse(myString)); What’s happening here? A string is defined containing a date. A new Date object is then defined using the … Read more

This guide will show you how to quickly and easily generate random numbers and strings in the JavaScript programming language. Generating random values is a common and important task when programming almost any kind of application of moderate complexity. Random strings and numbers are used to generate unique identifiers (e.g., for the short URLs in URL shortening services), for identifying unique records in a database, and (most importantly) are frequently used to determine the behavior of gameplay elements in video games (for example, simulating a … Read more

There are several ways to create text that spans multiple lines in JavaScript – so here they are! Method 1: Backticks This is the best method, so it goes first. It is only compatible with ECMAScript 6 and onwards, so it is only for use in modern browsers (really, if you’re using any browser that isn’t Internet Explorer, you should be fine, but you should always test your code on the browsers you want to target). var multiText = ` This is multiline text!`; console.log(multiText) // … Read more
