what is an object literal code example

Example 1: creating an object javascript

let obj = {
// fields
  name:"value",
  num: 123,
//methods
  foo: function(){}
  
}

Example 2: js objects

// To make an object literal:
const dog = {
    name: "Rusty",
    breed: "unknown",
    isAlive: false,
    age: 7
}
// All keys will be turned into strings!

// To retrieve a value:
dog.age; //7
dog["age"]; //7

//updating values
dog.breed = "mutt";
dog["age"] = 8;

Example 3: object literal javascript

// Object literals are defined using the following syntax rules:
// A colon separates property name from value.
// A comma separates each name-value pair from the next.
// There should be no comma after the last name-value pair.

// If any of the syntax rules are broken, such as a missing comma or colon or curly brace,
// an error will be thrown.

var myObject = {
    sProp: 'some string value',
    numProp: 2,
    bProp: false
};

Example 4: how to a property from a JavaScript object

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);

Example 5: literal object js

var car = {type:"Fiat", model:"500", color:"white"};
