Variables in standard JavaScript have no type attached, so any value (each value has a type) can be stored in any variable. Starting with ES6, the 6th version of the language, variables could be declared with var for function scoped variables, and let or const which are for block level variables.
So if you have nested functions, it is possible to use a variable without instantiating it with var but not be available globally, if there is an outer function in which that variable is defined.

^c The ALGOL 68, C and C++ languages do not specify the exact width of the integer types short, int, long, and (C99, C++11) long long, so they are implementation-dependent. In C and C++ short , long , and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more.
The Oxford comma is the comma used before the final conjunction in a list of three or more items. When writing a list, of course, you'll include commas to separate items and show individuality.
The functions in JavaScript are first-class objects, and therefore, first-class functions. First-class object entity which supports all the operations generally available to other entities (such as data types). These operations typically include being passed as an argument, returned from a function, modified, and assigned to a variable. In ...
The vertical bar represents an alternative and the terminal symbols are enclosed with quotation marks followed by a semicolon as terminating character. Hence a digit is a 0 or a digit excluding zero that can be 1 or 2 or 3 and so forth until 9. A production rule can also include a sequence of terminals or nonterminals, each separated by a comma:
