Javascript split string12/31/2022 ![]() In the second example, we are passing a regular expression as the argument for the split() method. 24 si gnihtyrevE dna ,esrevinU eht ,efiL fo noitseuQ etamitlU eht ot rewsnA ehT ![]() Split and reverse const reverse = paragraph.split( "").reverse().join( "") Split all characters, with a limit of 2 const firstTwoChars = paragraph.split( "", 2) Split by sentences const sentences = paragraph.split( //) Split by words const words = paragraph.split( " ") Now that we are comfortable with the use of the split() method, let's step it up a notch, and introduce regular expressions to the mix: const paragraph = `The Answer to the Ultimate Question of Life, the Universe, and Everything is 42. Regular Expressions with the split() Method The string will be broken down on every character: If we set the delimiter to something else, such as: const chars = str.split( "") Here, the string will be broken down on each new word: Setting limit=2, for example, will yield an array that contains the first two substrings separated by a delimiter in the original string: const str = "JavaScript is the best programming language!" The delimiter argument can also be specified as a regular expression, which will then be used to search through the original string to find delimiters that match the specified expression.Īdditionally, we can specify the optional argument limit, which specifies how many elements we want in our resulting substring array. JavaScript example for Capturing mouse positions. When the split(delimiter, limit) method is used on a string, it returns an array of substrings, and uses the delimiter argument's value as the delimiter. The delimiter is a string used as the delimiter for splitting. ![]() In this article we'll be taking a closer look at the split() method and how we can use it in conjunction with regular expressions to split a long string just the way we want. JavaScript has a lot of useful built-in methods for string manipulation, one of these method is the split() method.
