The replace Method

Substituting text

Replace part of a string:

let text = "Hello World"
console.log(text.replace("World", "JavaScript"))
// "Hello JavaScript"

By default, replace() only replaces the first occurrence:

let text = "cat cat cat"
console.log(text.replace("cat", "dog"))
// "dog cat cat"

To replace all occurrences, use replaceAll() or a regular expression with the global flag.
