How do I remove a property from a JavaScript object?

Question

Say I create an object as follows:

let myObject = {
  "ircEvent": "PRIVMSG",
  "method": "newURI",
  "regex": "^http://.*"
};

How should I remove the property regex to end up with new myObject as follows?

let myObject = {
  "ircEvent": "PRIVMSG",
  "method": "newURI"
};

Answer 1

To remove a property from an object (mutating the object), you can do it like this:

delete myObject.regex;
// or,
delete myObject['regex'];
// or,
var prop = "regex";
delete myObject[prop];

Demo

var myObject = {
    "ircEvent": "PRIVMSG",
    "method": "newURI",
    "regex": "^http://.*"
};
delete myObject.regex;

console.log(myObject);
