Replace all the roses with blackberry.

Replaces all the matches, not only the first match

To make the regular expression to replace all the occurrences, not only the first, we have to add flag g to the regular expression:

123

console.log("foo foo foo".replace(/foo/i, "bar")) // bar foo foo

console.log("foo foo foo".replace(/foo/gi, "bar")) // bar bar bar

console.log("foo1 foo2 foo3".replace(/foo(\d+)/gi, "$1")) // 1 2 3

If your regular expression includes capturing group, it will be reevaluated for every match:

console.log("foo1 foo2 foo3".replace(/foo(\d+)/gi, "$1")) // 1 2 3
