You can find more examples in the official documentation here.Remove All Whitespace From a String in JavaScript Or you can just chain it all together: const text = 'I love code! Code is great' const newStr = text.split( 'code').join( '')Ĭonsole.log(newStr) // I love ! Code is great const finalStr = newStr.join( '')Ĭonsole.log(finalStr) // I love ! Code is great You can then join the parts of the String using the method join(). The first is split(), which truncates a string when it finds a pattern (case sensitive) and returns an Array with the tokens:Įxample: const text = 'I love code! Code is great' const newStr = text.split( 'code')Ĭonsole.log(newStr) // console.log(newStr) // I love console.log(newStr) // ! Code is great To perform a case insensitive substitution, i.e., the method will not differentiate ‘code’ from ‘Code’, use the option i in regex: //gi String.replace( //gi, '')Įxample: const text = 'I love code! Code is great' const newStr = text.replace( /code/gi, '')Ĭonsole.log(newStr) //I love ! is great Replace Occurrences of a String Using split and joinĪn alternative, although slower than regex, is the use of two JavaScript functions. const text = 'I love code! Code is great' const newStr = text.replace( /code/g, '')Ĭonsole.log(newStr) //I love ! Code is great Here is an example where I replace all occurrences of the word “code” in the String text. That means “code” is different from “code”. This code above will perform a case sensitive replacement. If you want to replace all occurrences of a String this simple regex //g will do the job: String.replace( //g, '')

Example: var str = 'Let's eat something!' Ĭonsole.log(res) // Let's code something! Replace Occurrences of a String Using Regular Expressions The replace() method searches a string for a specified value, or a regular expression, and returns a new string where the specified values are replaced. Who commands the game here is the Javascript replace() method. Find out the proper way to replace occurrences of a String in JavaScript, using regex or other approaches.
