Where to learn more about object literal?

I don't quite understand object literal in the video. Dave said he would put a link in the teacher's note, but I didn't find it.

Does anybody know which video has a better explanation about object literal? Could you share the link?

Thank you.

Hey Yixi,

You could try having a look at the documentation here: https://learn.jquery.com/code-organization/concepts/ . I find that doing a google search really helps, I do this all the time when I get an unexpected error or need more more information when I am writing code. Hope this helps.

Regards,

Richard.

I took this course already, but I guess I didn't pay enough attention to the details. Thank you. I will review the object part again.

Not sure this will help you. I notice you already saw the videos. So I give it a try to explain...

In javascript, there are many ways to create an object. var car = new Object();

var car = { }; console.log(car); / Object

When javascript(Js) engine runs it is parsing the syntax, it come across this curly brace and equal operator = { }, it will know you are creating an object. You can initialize the object. You can set up properties and methods all in the curly braces on what is treated as one line of code.

-there is two properties on the car object... -make and model are known as key... put them together they are known as property... -Honda and Accord are known as value.... -the value of the property can be string, number , Boolean, another object, and array...

var car = {

    make : ‘Honda’,
    model : ‘Accord’
};

console.log(car); / /Object {brand: ‘Honda’, model : ‘Accord’ }

Let create a functions....and got deeper

The function will expect an object that has make property (created earlier), so I can call ride and pass in car 

function ride(drive){
    console.log(“I have a “ + drive.make);
}
ride(car); //"i have a Honda"

-call ride and pass in car -car is sitting in memory….than it get pass to the function and it able to be used -drive.make...

ride(car);
