In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement . Unlike other for loop constructs, however, foreach loops [ 1 ] usually maintain no explicit counter: they essentially say "do this to everything in this ...

This template implements a for loop or a foreach loop. This template calls a user-specified template (the "called template") multiple times: once for each value in either 1) an iterated sequence or 2) an explicit list. Each value in the sequence or list is passed to the same specified parameter of the called template (the "variable parameter").
The comprehension is implemented as a macro that is expanded at compile time, you can see the expanded code using the expandMacro compiler option: var collectResult = newSeq ( Natural ( 0 )) for item in items ( @[- 9 , 1 , 42 , 0 , - 1 , 9 ] ): add ( collectResult , item + 1 ) collectResult
Handlebars.js and Mustache are both logicless templating languages that keep the view and the code separated like we all know they should be. [8] Handlebars differs from its predecessor in that, within Block Expressions (similar to sections in Mustache), Helpers allow custom function through explicit user-written code for that block.
Then the condition is evaluated. If the condition is true the code within the block is executed again. This repeats until the condition becomes false. Do while loops check the condition after the block of code is executed. This control structure can be known as a post-test loop. This means the do-while loop is an exit-condition loop.
In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
The more correct form is for-loop with the hyphen (as well as while-loop, do-loop, do-while-loop, repeat-loop, foreach-loop, etc.), for exactly the reasons stated by NickyMcLean. The same goes for other constructs, such as if-then-else, do-while, repeat-until, try-catch, test-and-set, etc. It is indeed confusing to parse a sentence such as "for ...
