It\u2019s an anonymous\nfunction that\u2019s declared and invoked immediately after that. It\u2019s used in\nJavaScript to create a closed environment which can\u2019t be accessed from the\noutside.\n\n.. code-block::\n\n    // a and b can be accessed by external code\n    var a = 3,\n        b = 1;\n    // ... some code ...\n\n    // a and b can't be accessed by external code\n    (function() {\n        var a = 3,\n            b = 1;\n        // ... some code ...\n    })();\n\nWrapping code in an IIFE helps the minifier see the dead code, because it\n*knows* that these local variables can\u2019t be accessed from the outside and thus\ncan remove them or mangled their name.",
