const multiReplace = require('string-multiple-replace');

const input = "abcde";
const matcherObj = {

    "c": "d",
    "d": "e"
}
multiReplace(input, matcherObj, ["a", "b", "c", "d"]); // eeeee
multiReplace(input, matcherObj);                       // bcdee

• Example-1

const multiReplace = require('string-multiple-replace');

const input = "I'm only brave when I have to be. Being brave doesn't mean you go looking for trouble.";
const matcherObj = {
    "brave": "cowardly",
    "trouble": "escape"
}
const sequencer = ["brave", "trouble"];
multiReplace(input, matcherObj, sequencer);
//I'm only cowardly when I have to be. Being cowardly doesn't mean you go looking for escape.

• Example-2

}

multiReplace(input, matcherObj, keys => keys);
