And the split() method, of course, divides the string into an array. So far, we've learned how to split a string. How to Reverse an Array of Strings with the reverse() Method It does way more than just splitting a string: let myString = "Hello World" Ĭonsole.log() // The spread operator is an ES6 addition that makes it easy to split up a string into an array. How to Split String with the Spread Operator Then all we have to do is pass an empty string with no spaces, as seen below: let myString = "Hello World" Ĭonsole.log(myString.split("")) // Ĭonsole.log(myString.split(" ")) // In our case our string might be a regular string with nothing separating each character. The split() method is a very powerful method which you use to break a string into an ordered list of substrings based on a given pattern.įor example, if we have a sting of months separated by commas that we want to split up into an array of months, we could have something like this: const months_string = 'Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec' How to Split String With the split() Method There are two major methods of splitting a string in JavaScript: using the spread operator or the split() method. Let's try each of these methods separately. And finally, we join this array together as a string using the join() method. Then we use the reverse() method, which can only be used to reverse elements in an array. In general, we split the particular string into an array using either the spread operator or the split() method. This is because we will use only three methods that perform different functions and are all used together to achieve this one common goal. Using JavaScript methods to reverse a string is simple. How to Reverse a String With JavaScript Methods Let’s now discuss these methods and the role they play in helping us reverse strings in JavaScript. Or you can use this: let myReversedString =. We will learn how to reverse a string in JavaScript using built-in JavaScript methods as well as the JavaScript reverse() method in this article.įor those in a rush, here is one line of code to help you reverse a string in JavaScript: let myReversedString = myString.split("").reverse().join("") You might need to reverse a string during interviews, when solving algorithms, or when doing data manipulation. Reversing strings in JavaScript is something you'll need to do often on your web development journey.
