Wow...I was pretty suspicious about a claim to "Learn JavaScript in 12 Minutes", but you actually did a really good job of explaining a ton of material in a short amount of time.

In all honesty, you've actually explained it better than 2 weeks of my online class.

I know I'm late to the party, but I want to thank you, I watched your html and css videos, then I started learning Javascript with this video, I even bought the same book on ebay, let me tell you I never did any programming and web development before, and I'm glad I'm learning thanks to people like you, who share their knowledge with others, thanks a lot.

Why am I watching this, I do frontend web development for a living

Falcon-uxch

Man, you were not kidding, you DID cover the essence of coding in JS. As a raw beginner, I already feel like I am up and running in the language. Thank you!

This guy literally taught everything my introduction to software engineering class taught in one semester in 12 mins.. I was worried about passing the exam but less worried now

I love tutorials like this. Often, courses start with a long winded, slow introduction covering the basics that takes sometimes hours. I find however the best way to learn is by doing, especially with simple concepts, and a lot of the times it can just be learned as you work on more complicated uses.

evindrews

the fact that you condensed a 24 hour book (or atleast the important parts as you stated in the beginning) into 12 minutes and you did it well, im very impressed, i thank you for this tutorial

Love the easy pace and the depth out into each part, it makes it so much easier to comprehend!

Useful for people who already know Javascript.

1. // *Variables* (arithmetic)
<script>

var *num1* = *5;*
var *num2* = *3;*
var *total* = num1 + num2;
document.write(total);
= 8 in browser

</script>

2. // *Variables* (string/letters)
<script>

var *alpha* = "ABCDEFG";
var *length* = alpha.length;
document.write(length);
= 7 in browser (length of string aka amount of letters)

</script>

3. // *Arrays* (first, tedious method)
<script>

var a = *new* *Array* *[7]*
a[0] = "cat";
a[1] = "dog";
a[2] = 95;
a[6] = "true";
document.write(a[6]);
= "true" in browser

</script>

4. // *Arrays* (fastest method)
<script>

var a = *["cat", "dog", 95, true];* document.write(a[0]);

</script>

5. // *Functions*
<script>

(INSIDE <HEAD>) *function sayHello(who)* { document.write("Hello, " + who);
(OUTSIDE <HEAD>) sayHello("Bob"); document.write("<br>");
= "Hello, Bob" in browser

</script>

6. // *Conditional* ; if
<script>

var a = 7; *if* (a > 10) { alert(a);
} *else* { alert("The condition was false"); }

</script>

7. // *Conditional Loop* ; For()
<script>

for (i=0; i<5;i++)
{ document.write("This is iteration " + i + "<br>"); }

</script>

*Congratulations, you are now a JavaScript Expert!*
