JavaScript, often abbreviated as JS, is a programming language that conforms
to the ECMAScript specification.
JavaScript is high-level, often just-in-time compiled, and multi-paradigm.
It has curly-bracket syntax, dynamic typing, prototype-based object-orientation,
and first-class functions.

var a = [
  "We're up all night 'til the sun",
  "We're up all night to get some",
  "We're up all night for good fun",
  "We're up all night to get lucky"
];

// Sans la syntaxe des fonctions fléchées 
var a2 = a.map(function (s) { return s.length });
// [31, 30, 31, 31]

// Avec, on a quelque chose de plus concis
var a3 = a.map( s => s.length);
// [31, 30, 31, 31]

JavaScript is a text-based programming language used both on the client-side
and server-side that allows you to make web pages interactive.
Where HTML and CSS are languages that give structure and style to web pages,
JavaScript gives web pages interactive elements that engage a user.

Operator	Example	Same As
=	x = y	x = y
+=	x += y	x = x + y
-=	x -= y	x = x - y
*=	x *= y	x = x * y
/=	x /= y	x = x / y
%=	x %= y	x = x % y
**=	x **= y	x = x ** y
