A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
Syntax highlighting and indent style are often used to aid programmers in recognizing elements of source code. This Python code uses color-coded highlighting. In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in ...
A block is a grouping of code that is treated collectively. Many block syntaxes can consist of any number of items (statements, expressions or other units of code) – including one or zero. Languages delimit a block in a variety of ways – some via marking text and others by relative formatting such as levels of indentation.
The eval function is a function that converts and interprets a string as actual JavaScript code, and runs that code. If that string is specified as a literal , then the code must be written as a quote itself (and escaped accordingly).

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).
However, if your code works with the content part of the page (the #mw-content-text element), you should use the 'wikipage.content' hook instead. This way your code will successfully reprocess the page when it is updated asynchronously and the hook is fired again. There are plenty of tools that do so, ranging from edit preview to watchlist ...
JSFuck can be used to bypass detection of malicious code submitted on websites, e.g. in cross-site scripting (XSS) attacks. [10] Another potential use of JSFuck lies in code obfuscation. An optimized version of JSFuck has been used to encode jQuery, a JavaScript library, into a fully functional version written with just the six characters. [11]
