To replace all occurrences of a string in JavaScript, you can use the replace() method with a regular expression and the g flag. The g flag stands for "global" and will replace all occurrences of the string instead of just the first one.

let originalString = "Hello world, hello universe!";

In this example, the replace() method is called on the originalString variable with the regular expression /hello/gi and the replacement string "hi". The g flag is used to replace all occurrences of the string, and the i flag is used to make the search case-insensitive. The resulting string, "Hi world, hi universe!", is then assigned to the newString variable and printed to the console.

Note that replace() does not modify the original string. Instead, it returns a new string with the replacements made. If you want to modify the original string, you can assign the result back to the original variable:
