![]() If the last character is not a number, it will not replace. Str.replace( /\d$/, '') // Masteringjs.io let str2 = 'Masteringjs.io0F' , itemX) Parameters Return Value An array containing the removed items (if any). The splice () method overwrites the original array. With replace(), you can specify if the last character should be removed depending on what it is with a regular expression.įor example, suppose you want to remove the last character only if the last character is a number. The splice () method adds and/or removes array elements. Str.replace( /.$/, '') // Masteringjs.io Advanced Features ![]() Str.substr( 0, str.length - 1) // Masteringjs.io Str.substring( 0, str.length - 1) // Masteringjs.io replace(/.$/, '') replaces the last character of the string with an empty string. Using /.$/ as the regular expression argument matches the last character of the string, so. ![]() Replace() takes either a string or a regular expression as its pattern argument. Substring() does not have negative indexing, so be sure to use str.length - 1 when removing the last character from the string. This method modifies the original array and returns the removed elements as a new array. It lets you change the content of your array by removing or replacing existing elements with new ones. Slice() is generally easier, however other methods available are substring() and replace(). The splice() method is a built-in method for JavaScript Array objects. Str.slice( 0, -1) // Masteringjs.io Alternative Methods Slice() supports negative indexing, which means that slice(0, -1) is equivalent to slice(0, str.length - 1). It takes two arguments: the start index and the end index. To remove the last character from a string in JavaScript, you should use the slice() method.
