Either I watched these tutorials before and don't remember at all or you use almost all the same examples as you did in PHP... I hope i didn't watch all of these before because don't remember watching javascript tutorials.

[MLPComputerTutorials]

How do you let the user choose the name? If they don't know JavaScript

[TheHiguty]

@MLPComputerTutorials You would use XHTML to receive input (or maybe PHP as well, idk) and then give the inputted text to the program. Bucky didn't do all that stuff to save time

[elvisniperx]

var girl = "Bucky";

function x(a, b){ case a: document.write(b);

}

switch(girl){ x("Bucky","Ya, thats a girl"); x("Robin","He is cool"); x("Sonja","Thats the name of my mother"); x("She-male","Thats not a girl"); x("Lesbian","They love girls"); x("XD","Thats not a name of a girl!"); x("this is madness","THIS IS MADDNEEES"); default: document.write("Bucky is a girl!");}

@AOERyan I think he got kicked in the throat before doing these last couple tutorials.

Who is this @kidel3 guy?

[kidel3]

OK, to explain the "case" and "default" (+ break) a bit more. The "case" is like an if statement, if the case equals (variable) to a value, it will execute the code inside (document.write in this case), but the "default" is like an else statement (not "else if") where you can execute some code if there isn't any matches for the cases. And to the break. If the client found a case that matched the variable, it stops searching for a new one. Easy explained. Hope you all understood quite well.

[FHomeBrew]

What if we remove the "break;" statements?

[JavaFolower]

@FHomeBrew the switch statement will continue and if it will find another true case it will execute whats in that case. example:

var x = 50;

switch(x){ case 50: do a stuff;  case 250: do b stuff; case 50: do c stuff; default: do d stuff;

}

this will do a and(!) c stuff

[FHomeBrew]

@JavaFolower In Java (long time since I last used that) the switch cases would just cascade until the next break. Regardless of if the case was true or not. At least, that's how I remember it. Never used switch cases that much since I can use math to work around that.

[Kryppuk]

@FHomeBrew

Everything below the statement that gets selected is executed, even if the condition isn't true, until it reaches a "break;" or the end.

[kidel3]

@FHomeBrew Try it then. You'll like the results.

[Bladestorm687]

@FHomeBrew Then it would just run the code over and over.

[FHomeBrew]

@Bladestorm687 It would eventually run into the "default" statement (which is what it should do when none of the cases matches. That might even need a "break" though. However, since the switch-case construct is not a loop, it won't run forever would it?

[evothepker]

Great job with these tutorials. Makes learning much entertaining and interesting.
