    An Array is a JavaScript object prototyped from the Array constructor specifically designed to store data values indexed by ... // Concatenate 2 strings console. log ...

  3. Comparison of programming languages (string functions)

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

    For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.

  4. Comparison of programming languages (strings) - Wikipedia

    Rexx uses this syntax for concatenation including an intervening space. C (along with Python) allows juxtaposition for string literals, however, for strings stored as character arrays, the strcat function must be used. COBOL uses the STRING statement to concatenate string variables. MATLAB and Octave use the syntax "[x y]" to concatenate x and y.

  5. Comparison of programming languages (associative array)

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

    The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:

  6. JavaScript - Wikipedia

    en.wikipedia.org/wiki/JavaScript

    JavaScript is weakly typed, which means certain types are implicitly cast depending on the operation used. [58] The binary + operator casts both operands to a string unless both operands are numbers. This is because the addition operator doubles as a concatenation operator; The binary -operator always casts both operands to a number

  7. Rope (data structure) - Wikipedia

    en.wikipedia.org/wiki/Rope_(data_structure)

    Array-based strings have smaller overhead, so (for example) concatenation and split operations are faster on small datasets. However, when array-based strings are used for longer strings, time complexity and memory use for inserting and deleting characters becomes unacceptably large.

  8. Concatenation - Wikipedia

    en.wikipedia.org/wiki/Concatenation

    The strings over an alphabet, with the concatenation operation, form an associative algebraic structure with identity element the null string—a free monoid. Sets of strings with concatenation and alternation form a semiring, with concatenation (*) distributing over alternation (+); 0 is the empty set and 1 the set consisting of just the null ...
