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 article will show you the ways to convert an object to an array in JavaScript – quickly and easily. There are many ways to convert objects to arrays, but these (should) be the most straightforward methods. Converting Object to Array in JavaScript – Values Only If you only need the values from the object, the Object.values() method will extract them into an array: var myObject = { colour: ‘blue’, number: 43, name: ‘Fred’, enabled: true }; var values = Object.values(myObject); console.log(values); The above will return an array with … Read more

The Object.entries() method in JavaScript can be used to convert an object to an array – but it doesn’t work recursively. So here’s a function to accomplish that. I can’t think of a reason why you’d want to do this, but it came up while putting together an article on using Object.entries() – so here it is! Recursive Function for Converting Objects to Arrays I’ll let the comments do the talking as to what’s going on. The gist of it is that (for whatever reason) you want to convert an … 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
