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 .
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.
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 ...
String functions common to many languages are listed below, including the different names used. The below list of common functions aims to help programmers find the equivalent function in a language. Note, string concatenation and regular expressions are handled in separate pages.
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
A concatenation can be performed simply by creating a new root node with left = S1 and right = S2, which is constant time. The weight of the parent node is set to the length of the left child S 1 , which would take O ( log N ) {\displaystyle O(\log N)} time, if the tree is balanced.

String concatenation is an associative, but non-commutative operation. The empty string ε serves as the identity element ; for any string s , ε s = s ε = s . Therefore, the set Σ * and the concatenation operation form a monoid , the free monoid generated by Σ.
