There are several ways to use change parts of a string in JS. The basic syntax ONLY replaces the first instance of the string:
let prose = prose.replace("twat", "fool");
The replaceAll() method
The replaceAll() method changes all instances of a string.
uses the new replaceAll method.
function replaceMe() {
let firstName = prompt("whats yor name?");
alert("Welcome home " + firstName.replaceAll('e', 'a'));
}
The older way to replace all
According to A Smarter Way to Learn Javascript you replace all instances by changing the quotes in the word to remove with forward slashes and the letter g:
let fineProse = fineProse.replace(/fuckhead/g, "silly man");
This replaces the word fuckhead with silly man.
let poetry = poetry.replaceAll("farted", "broke wind");
uses the /first word/g method.
function changeMe() {
let name = prompt("whats yor name?\n\(Never use yor reael name on the interent\)");
alert("Welcome home " + name.replace(/e/g, "a"));
}
