Editor's Notes
- #2: Quick language poll How many people have heard of Angular? jQuery? Node? React? ES6? These are just JS!
- #4: Unique compared to other langs: runs directly in the browser, nothing else needed Chrome, FF, IE Syntax similar to other languages, a great starting point to learn others
- #6: What do people use JS for? Runs in the browser = used for websites!
- #7: Without JS, the web is more boring Front end JS
- #8: Backend: LinkedIn Mobile: Facebook
- #11: Flash and Java applets started to decline, because of security and convenience People started realizing you could use JavaScript to do the same things
- #12: As it evolved, it became more and more relevant Because...
- #14: One measure of a language’s importance is how many devices it can run on Every single web browser in the world - over 2 billion PCs Billions of phones
- #17: The majority of front-end developer jobs are JavaScript or include JavaScript More and more back-end developer jobs are JavaScript, but not all Some companies do full-stack JS - full-stack engineers are super valuable!
