    Lacking the distinct features of "usual" JavaScript, obfuscation techniques like JSFuck can assist malicious JavaScript code in bypassing intrusion prevention systems [17] or content filters. For instance, the lack of alphanumeric characters in JSFuck and a flawed content filter allowed sellers to embed arbitrary JSFuck scripts in their eBay ...

    ^c Subranges are used to define the bounds of the array. ^d JavaScript's array are a special kind of object. ^e The DEPENDING ON clause in COBOL does not create a true variable length array and will always allocate the maximum size of the array.

    The following list contains syntax examples of how a range of element of an array can be accessed. In the following table: first – the index of the first element in the slice

  5. Comparison of programming languages (associative array)

    en.wikipedia.org/wiki/Comparison_of_programming...

    In modern JavaScript it's considered bad form to use the Array type as an associative array. Consensus is that the Object type and Map / WeakMap classes are best for this purpose. The reasoning behind this is that if Array is extended via prototype and Object is kept pristine, for and for-in loops will work as expected on associative 'arrays'.

    Set a bucket length array to record the length of the unsorted bucket. Initialize into the original array length. [Main Sort] If the bucket length array is cleared and sorted is completed. Execute [Divide function] if it is not cleared. [Divide function] Execute Divide by pop a bucket length from the end of the bucket length array.

    The program can create a complete text representation of any group of objects by calling these methods, which are almost always already implemented in the base associative array class. [ 23 ] For programs that use very large data sets, this sort of individual file storage is not appropriate, and a database management system (DB) is required.

    PHP treats newlines as whitespace, in the manner of a free-form language. The concatenation operator is . (dot). Array elements are accessed and set with square brackets in both associative arrays and indexed arrays. Curly brackets can be used to access array elements, but not to assign.

  9. Array (data type) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_type)

    In computer science, array is a data type that represents a collection of elements (values or variables), each selected by one or more indices (identifying keys) that can be computed at run time during program execution. Such a collection is usually called an array variable or array value. [1]
