Bracket matching, also known as brace matching or parentheses matching, is a syntax highlighting feature of certain text editors and integrated development environments that highlights matching sets of brackets (square brackets, curly brackets, or parentheses) in languages such as Java, JavaScript, and C++ that use them. The purpose is to help ...
Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP. PHP supports standard C/C++ style comments, but supports Perl style as well. Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19]
A curly bracket or curly brace language has syntax that defines a block as the statements between curly brackets, a.k.a. braces, {}. This syntax originated with BCPL (1966), and was popularized by C. Many curly bracket languages descend from or are strongly influenced by C. Examples:
More generally, curly braces are used to group words together into a single argument. [ 10 ] [ 11 ] In Tcl, the word while takes two arguments, a condition and an action . In the example above, while is missing its second argument, its action (because the Tcl also uses the newline character to delimit the end of a command).
In the language Scala, early versions allowed curly braces only. Scala 3 added an option to use indenting to structure blocks. Designer Martin Odersky said that this was the single most important way Scala 3 improved his own productivity, that it makes programs over 10% shorter and keeps programmers "in the flow", and advises its use.

Curly braces delimit angled brackets to prevent the formation of a tag, so the easiest way to escape tags is with undefined parameter defaults. This does not have the overhead of a template call. Example: {{{|<}}}example/{{{|>}}} After the first substitution: <example/> Tags can be escaped much like braces.
A snippet of JavaScript code with keywords highlighted in different colors 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 .
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.
