How can I use goto in Javascript?

Absolutely! There is a project called http://summerofgoto.com/ that allows you use Javascript at it's fullest potential and will revolutionize the way you can write your code. This Javascript preprocessing tool allows you to create a label and then goto it using this syntax: [lbl] <label-name> goto <label-name> For example, the example in the question can be written as follows: [lbl] start: alert("LATHER"); alert("RINSE"); [lbl] repeat: goto start; http://jsfiddle.net/dBUAL/, but be warned that it will be an infinite loop and you might have to forcefully shut down your browser to get out of it. Note that you are not just limited to simple trivial programs like an endless LATHER RINSE repeat cycle--the possibilities afforded by goto are endless and you can even make a Hello, world! message to the Javascript console 538 times, like this: var i = 0; [lbl] start: console.log("Hello, world!"); i++; if(i < 538) goto start; Again, you can http://jsfiddle.net/knLGk/, and this time you don't have to worry about having to end the program forcefully. http://alexsexton.com/?p=11, but basically, it does some Javascript preprocessing that takes advantage of the fact that you can simulate a goto with a https://developer.mozilla.org/en/JavaScript/Reference/Statements/label. So, when you write the "Hello, world!" program above, it gets translated to something like this: var i = 0; start: while(true) { console.log("Hello, world!"); i++; if(i < 538) continue start; break; } There are some limitations to this preprocessing process, because while loops cannot stretch across multiple functions or blocks. That's not a big deal, though--I'm sure the benefits of being able to take advantage of goto in Javascript will absolutely overwhelm you.

How about a for loop? Repeat as many times as you like. Or a while loop, repeat until a condition is met. There are control structures that will let you repeat code. I remember GOTO in Basic... it made such bad code! Modern programming languages give you better options that you can actually maintain.

You should probably read some JS tutorials like this http://en.wikibooks.org/wiki/JavaScript/Control_Structures. Not sure if goto exists in JS at all, but, either way, it encourages bad coding style and should be avoided. You could do: while ( some_condition ){ alert('RINSE'); alert('LATHER'); }

Generally, I'd prefer not using GoTo for bad readability. To me, it's a bad excuse for programming simple iterative functions instead of having to program recursive functions, or even better (if things like a Stack Overflow is feared), their true iterative alternatives (which may sometimes be complex). Something like this would do: while(true) { alert("RINSE"); alert("LATHER"); } That right there is an infinite loop. The expression ("true") inside the parantheses of the while clause is what the Javascript engine will check for - and if the expression is true, it'll keep the loop running. Writing "true" here always evaluates to true, hence an infinite loop. A similar example (to explain these conditions and the while clause), the following would be the same: while(2 + 2 == 4) { alert("RINSE"); alert("LATHER"); } One could (however) argue why you need an infinite loop of alert boxes. I hope you're using this for something good, not for something bad.
