Javascript: You Like It, It Likes You

The slide deck from a "Javascript For Beginners" training session I ran in our office earlier this year. Of course, some of the slides won't make sense out of context, but whatevs, right?

Also, be warned that I was pretty sleep-deprived when this all happened, and a side effect of that was that I swore a LOT during the presentation. Some of that leaked it's way into the slide deck. Maybe don't show this to your mom.

18. Tuesday, 27 September, 11
19. DON’T FUCKING DO THIS. Tuesday, 27 September, 11
20. DON’T FUCKING DO THIS. p.s.: yeah. i wrote it. shut up. Tuesday, 27 September, 11
21. Arithmetic Operators Tuesday, 27 September, 11
22. Variables and data types. Tuesday, 27 September, 11
23. Variables and data types. Tuesday, 27 September, 11
24. Variables and data types. String theory. Tuesday, 27 September, 11
25. Variables and data types. Hey baby what’s your Number. Tuesday, 27 September, 11
26. Variables and data types. Stupid loose typing. Wait, it gets better. Tuesday, 27 September, 11
27. Variable comparisons. Tuesday, 27 September, 11
28. x = 4; y = “7”; x.toString(); // “4” (string) parseInt(y,10); // 7 (number) Variable comparisons. Tuesday, 27 September, 11
29. y = “why”; parseInt(y,10); // NaN (Not a Number) Variable comparisons. Tuesday, 27 September, 11
30. NaN == NaN; NaN === NaN; // both false. Variable comparisons. This is why Douglas Crockford drinks. Tuesday, 27 September, 11
31. Note that +, besides being used for math, also concatenates strings. ! ! ! ! ! var x = 5 + 3; !! ! ! // 8 - Number ! ! ! ! ! var x = “5” + “3”; !! // “53” - String (PHP got this part right. JavaScript? Meh.) Variable comparisons. This is why Scott Kosman drinks. Tuesday, 27 September, 11
32. Variables and data types. Boolean. That word’s funny enough on it’s own. Tuesday, 27 September, 11
