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 ...
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 ...
The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. The examples below make use of the log function of the console object present in most browsers for standard text output. The JavaScript standard library lacks an official standard text output function (with the exception of document.write).

The following example is done in Ada which supports both early exit from loops and loops with test in the middle. Both features are very similar and comparing both code snippets will show the difference: early exit must be combined with an if statement while a condition in the middle is a self-contained construct.
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").
There are many Mustache Engine implementations available, and all of them meet a common formal specification (see external links), that for final users results in the common syntax. As of March 2011, the last SPEC_VERSION was 1.1.2. [6] All Mustache Engines, in the v1.X architecture, have a render method, a Mustache_Compiler class and a Parser ...
Nested functions can be used for unstructured control flow, by using the return statement for general unstructured control flow.This can be used for finer-grained control than is possible with other built-in features of the language – for example, it can allow early termination of a for loop if break is not available, or early termination of a nested for loop if a multi-level break or ...
