Starting JavaScript (JS)

Front-end web programming crash course

 

Zach Saucier

What more conventional programming looks like

Feel free to use your laptops

Variables, Types, Comments

If, else, else if

If, else, else if

also switch

What is the value of a? of b?

Console

Right click -> Inspect element -> console

or 

F12

or 

Ctrl (cmd) + shift + i

While loops

also do-while

For loops

Generally used over while

That's the majority of programming logic!

Structures that help us stay generic

(this is a good thing!)

Problem:

Functions

Saves us from rewriting something every time

Problem:

How can we fix this?

Arrays

No matter how many buttons we have, this applies to all of them!

Yay for saving us work!

Arrays (cont.)

Arrays can have whatever we want in them

Arrays can be nested. Remember what that means?

Problem:

There are lots of problems when programming, huh?

Objects

That's all the structures we need

Interacting with other things on our page

Selecting/Editing elements

Events

Editing the DOM

That's about it for interacting with elements

Now what?

Some other things worth mentioning

Scoping

True for functions, loops, if/else

Error handling

More complex condition checking

Alternative values

That's about it :)

Next week we'll get things moving!
Animations!

Project time!
