If fromIndex is not present, all values in the array will be searched and the array will be treated as a table/associative array (it will be iterated over using pairs ()). If fromIndex is present and an integer, the array is assumed to be a conventional array/sequence/list (indexed with consecutive integer keys starting at 1 , and interated ...
Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments, however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.
In object-oriented languages, string functions are often implemented as properties and methods of string objects. In functional and list-based languages a string is represented as a list (of character codes), therefore all list-manipulation procedures could be considered string functions. However such languages may implement a subset of ...

Its features include exponentiation operator ** for numbers, await, async keywords for asynchronous programming (as a preparation for ES2017), and the Array.prototype.includes function. [5] The exponentiation operator is equivalent to Math.pow, but provides a simpler syntax similar to languages like Python, F#, Perl, and Ruby.
When an object is declared in a parameterized constructor, the initial values have to be passed as arguments to the constructor function. The normal way of object declaration may not work. The constructors can be called explicitly or implicitly. The method of calling the constructor implicitly is also called the shorthand method.
In languages with single dispatch, classes typically also include method definitions. In languages with multiple dispatch, methods are defined by generic functions. There are exceptions where single dispatch methods are generic functions (e.g. Bigloo's object system).
Whereas Prototype extended—prototyped—many of JavaScript's native String, Array, and Function objects with additional methods, Proietti desired a framework that (at the time) [15] further extended the native Element object as well [13] to offer greater control of the Document Object Model (DOM).
