Most programming languages with control structures have an initial keyword which indicates the type of control structure involved. [clarification needed] Languages then divide as to whether or not control structures have a final keyword. No final keyword: ALGOL 60, C, C++, Go, Haskell, Java, Pascal, Perl, PHP, PL/I, Python, PowerShell. Such ...
In Mozilla's JavaScript, since version 1.7, destructuring assignment allows the assignment of parts of data structures to several variables at once. The left hand side of an assignment is a pattern that resembles an arbitrarily nested object/array literal containing l-lvalues at its leaves that are to receive the substructures of the assigned ...
The fork–join model from the 1960s, embodied by multiprocessing tools like OpenMP, is an early example of a system ensuring all threads have completed before exit.. However, Smith argues that this model is not true structured concurrency as the programming language is unaware of the joining behavior, and is thus unable to enforce

In computer programming, a loop counter is a control variable that controls the iterations of a loop (a computer programming language construct). It is so named because most uses of this construct result in the variable taking on a range of integer values in some orderly sequences (for example., starting at 0 and ending at 10 in increments of 1)
first checks whether x is less than 5, which it is, so then the {loop body} is entered, where the printf function is run and x is incremented by 1. After completing all the statements in the loop body, the condition, (x < 5), is checked again, and the loop is executed again, this process repeating until the variable x has the value 5.

Closures are also often used with callbacks, particularly for event handlers, such as in JavaScript, where they are used for interactions with a dynamic web page. Closures can also be used in a continuation-passing style to hide state. Constructs such as objects and control structures can thus be implemented with closures. In some languages, a ...
