How to replace using regex?

Question

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?

You can use replace of JavaScript like str.replace("figure figure watch?v=", "ifigure ifigure embeded/"); — Wajid

[{"figure figure watch?v="}, {"figure data watch?v="}] gives a syntax error. What actual input do you have? Is it [ "figure figure watch?v=", "figure data watch?v=" ] ? — Peter Thoeny

Yes [ "figure figure watch?v=", "figure data watch?v=" ] this — Shahariar Rahman Sajib

You need to check if data is available like if(res){ //do here logic} — Wajid

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/"]

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];
})));
