To remove the last character from a string in JavaScript, you should use the slice() method. It takes two arguments: the start index and the end index. slice() supports negative indexing, which means that slice(0, -1) is equivalent to slice(0, str.length - 1).
let str = Masteringjs.ioF; str.slice(0, -1); Alternative Methodsslice() is generally easier, however other methods available are substring() and replace()[1]. substring() does not have negative indexing, so be sure to use str.length - 1 when removing the last character from the string. replace() takes either a string or a regular expression as its pattern argument. Using /.$/ as the regular expression argument matches the last character of the string, so .replace(/.$/, ) replaces the last character of the string with an empty string.
let str = Masteringjs.ioF; str.substring(0, str.length - 1); str.substr(0, str.length - 1); str.replace(/.$/, ); Advanced Feature...
