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 set", rather than "do this x times". This avoids potential off-by-one errors and makes code simpler to read.
In the ECMAScript example, return x will leave the inner closure to begin a new iteration of the forEach loop, whereas in the Smalltalk example, ^x will abort the loop and return from the method foo. Common Lisp provides a construct that can express either of the above actions: Lisp (return-from foo x) behaves as Smalltalk ^x , while Lisp ...
If the foreach is moved to a separate script, piping works because scripts are run by forking a new copy of csh that does inherit the correct stdio handles. It's also possible to break codes in a single file. An example is given below on how to break codes in a single file.) Another example is the unwelcome behavior in the following fragments.
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.
INT sum sq := 0; FOR i WHILE print(("So far:", i, new line)); # Interposed for tracing purposes. # sum sq ≠ 70↑2 # This is the test for the WHILE # DO sum sq +:= i↑2 OD Subsequent extensions to the standard ALGOL 68 allowed the to syntactic element to be replaced with upto and downto to achieve a small optimization. The same compilers ...

C++ added support for async/await with version 20 in 2020 with 3 new keywords co_return, co_await, co_yield. Swift added support for async/await with version 5.5 in 2021, adding 2 new keywords async and await .
utility is a header file in the C++ Standard Library. This file has two key components: This file has two key components: rel_ops , a namespace containing set of templates which define default behavior for the relational operators != , > , <= , and >= between objects of the same type, based on user-defined operators == and < .
