Why Learn JavaScript as a Beginner?

JavaScript brings web pages to life through interactivity. As a front-end language, it handles:

Animations, slideshows, scroll effects
Interactive maps like Google Maps
Form validation and display of dynamic content
Drawing graphics and chart visualizations
Single page applications and modern UI features

With the Node.js runtime, JavaScript extends beyond the browser to:

Build fast and scalable server-side applications
Develop cross-platform desktop apps using Electron
Write mobile apps with React Native
Control IoT devices and robots like drones
Run TensorFlow machine learning models

Some key advantages of learning JavaScript first:

Beginner-friendly syntax adapted from C and Java
Can instantly see results by manipulating web pages
Huge community with abundant learning resources
In-demand job skill – Over 245,000 JS job openings on Indeed
Opens door to popular JS frameworks like React and Angular
Transferrable skill works across frontend, backend, and app dev

Let‘s briefly cover how we got to the JavaScript landscape today.

A Brief History of JavaScript

In 1995, Netscape developer Brendan Eich created JavaScript to make web pages more interactive. The lineage goes like:

1995 – Officially named JavaScript, adopted in Netscape Navigator
1997 – Standardized as ECMAScript by Ecma International
2005 – AJAX introduced for asynchronous server communication
2009 – Node.js allows JS to run on servers via Chrome‘s V8 engine
2011 – HTML5 provides more JavaScript APIs to access browser features
2015 – Release of ES6/ES2015, a major update adding classes, promises, arrow functions and more
2022 – 97.6% of websites use JavaScript code according to W3Techs

Over the years, JavaScript has evolved from controlling simple animations to powering entire applications. Let‘s overview some of the core concepts you‘ll want to get comfortable with.

Core JavaScript Concepts

While I‘ll point you to resources that cover JS from A to Z, here‘s a quick rundown of some core topics to understand:

Variables – Store values like numbers and text
Data types – Primitive types like strings, numbers, booleans
Operators – Symbols for actions like +, -, ===
Functions – Reusable blocks of code
Conditionals – Make decisions with if/else statements
Loops – Repeat code like for and while loops
Arrays – Ordered lists to store data
Objects – Unordered complex data structures
DOM – Manipulate HTML/CSS dynamically via the Document Object Model
Events – Listen for interactions like clicks
Asynchronous – Manage non-blocking code execution like promises

This sums up the basics, but you’ll eventually get into object-oriented programming, functional programming, web APIs, modules, build tools, and more!

Now let‘s dive into the best online courses, tutorials, and learning resources for mastering JavaScript…

Top JavaScript Courses & Tutorials Reviews

Over the past 5 years I‘ve gone through my fair share of books, video courses, and docs while learning JavaScript. Here are the ones I highly recommend:

FreeCodeCamp

FreeCodeCamp is a free, open source coding bootcamp accessible right from your browser. Instead of videos, their curriculum uses interactive coding challenges to teach you concepts.

My thoughts:

Completely free and self-paced
Browser-based challenges were conducive to learning
Active forums if you ever need hints or help
Covers both foundations and front-end development
Got to build portfolio projects along the way

I appreciated their hands-on, project-driven approach as it really cemented my understanding. Their curriculum is also totally customizable, letting you skip topics you already know.

Codecademy

Codecademy has interactive JavaScript courses where you write code right in the browser.

What I liked:

Bite-sized lessons I could do daily
Quizzes reinforced key concepts
Built-in console helped debug code

Certificates of completion to showcase on LinkedIn

With engaging video instruction and coding exercises, Udemy helped strengthen areas I was shaky on. Their courses also update frequently with the latest JS features.

Eloquent JavaScript

For an in-depth book on both JavaScript fundamentals and advanced concepts, Eloquent JavaScript by Marijn Haverbeke is my top pick.

Why it‘s so highly praised

Thorough coverage of core topics like functions, data structures
Dives into object-oriented and functional programming
Excellent chapter on async JavaScript

I really appreciated the book‘s deep dives into complex topics that most courses don‘t cover. And the electronic version is free!

YouTube Channels

YouTube is a goldmine of JavaScript video tutorials. Here are 3 great channels I recommend:

Freecodecamp – Great for total beginners new to coding
The Net Ninja – Fun tutorials on web dev topics
Academind – High quality videos on JS concepts

Why YouTube worked for me:

Visual explanation of concepts helped cement them
Ability to replay videos and learn at my own pace

Tips for Learning JavaScript Effectively

Here are some tips and tricks based on my experience that can help expedite your JavaScript learning:

Code daily – Regular practice is key even if for just 30 mins
Build projects – Apply your knowledge by making mini-apps
Use documentation – Get familiar with MDN and learning to search API docs
Take handwritten notes – This sticks better than typed notes for some
Explain code out loud – Verbalizing it helps solidify concepts
Get help – Ask questions on StackOverflow, Reddit, forums
Pair program – Code alongside other students
Immerse yourself – Watch/listen to JavaScript videos and podcasts daily
Make it fun – Learn through games and making memes

Beyond just passively consuming content, it‘s critical to actively reinforce concepts through projects. Teaching others is also one of the best ways to learn.
