), exclamation mark ( !), a question mark ( ?) or three dots (. For instance, say you'd like to break a string into sentences. You can't match by multiple delimiters, unless you use a Regular Expression. One of the major downsides of using single characters or even entire strings is that the approach is fairly rigid. We could split it on each whitespace (breaking it down into words), or on every character, or any other arbitrary delimiter, such as 'p': // Split string using a whitespace let array1 = quote.split( ' ') Ĭonsole.log(array1) // // Splitstring using an empty string (on each character) let array2 = quote.split( '') Ĭonsole.log(array2) // // Split string using a specific character let arra圓 = quote.split( 'p') Ĭonsole.log(arra圓) // If you'd like to learn more about Regular Expressions - read our Guide to Regular Expressions and Matching Strings in JavaScript!įor example, suppose we have a string: let quote = 'I am unstoppable!' The pattern/divider/delimiter is the first parameter in the method's call and can be a regular expression, a single character, or another string. The split() method is used to divide a string into an ordered list of two or more substrings, depending on the pattern/divider/delimiter provided, and returns it.

In this guide, learn how to convert a String to an Array in JavaScript, with the split(), Object.assign(), om() methods and spread operator, as well as when to use which. Whether you're breaking a word down into its characters, or a sentence into words - splitting a string into an array isn't an uncommon operation, and most languages have built-in methods for this task. These sequences, are ultimately, arrays, and converting between the two structures typically is both simple and intuitive. Textual data is typically stored through sequences of characters - strings.
