How to replace using regex?

var result = [{"figure figure watch?v="}, {"figure data watch?v="}]
console.log(result.replace(res=> res.('figure', 'ifigure', 'watch?v=' , 'embeded/')))

I want result = [{"ifigure ifigure embeded/"}, {"ifigure data embeded/"}]

Can you help?

First of all [{"ifigure ifigure embeded/"}, {"ifigure data embeded/"}] you have a syntax error here. you cannot enclose string in an object. you will need to do something like this. if in future you want to replace new string, just add them in this object.

var mapObj = {
   'watch?v=':"embeded/",
   'figure':"ifigure"
};

var result = ["figure figure watch?v=", "figure data watch?v="];
console.log(result.map(res=> res.replace(/watch\?v=|figure/gi, function(matched){
  return mapObj[matched];
})));

The simplest way will be to use Array.map method with regex -

var result = ["figure figure watch?v=", "figure data watch?v="];
result.map(e => e.replace(/watch\?v=/g, "embeded/").replace(/figure/g, "ifigure"));
// (2) ["ifigure ifigure embeded/", "ifigure data embeded/"]
