Au d\u00e9but des ann\u00e9es 90 Tim Berners-Lee inventa le\u00a0World Wide Web\u00a0(www), qui\u00a0est un r\u00e9seau de documents (pages web : la home page du lyc\u00e9e par exemple) r\u00e9partis dans le r\u00e9seau internet, qui a aussi \u00e9volu\u00e9 en un r\u00e9seau d’acc\u00e8s \u00e0 des applications (pages web dynamiques : google.com, amazon.com, youtube.com, \u2026).\u00a0\u00a0<\/span><\/p>\n

Pour faire fonctionner cette toile globale de nouveaux langages ont \u00e9t\u00e9 imagin\u00e9s. Je vais parler de deux d’entre eux.\u00a0<\/span><\/p>\n

HTML:\u00a0<\/span><\/h1>\n

HTML\u00a0aussi appeler L\u2019HyperText Markup Langage est le format le plus souvent utilis\u00e9\u00a0pour cr\u00e9er des sites web. HTML a \u00e9t\u00e9 invent\u00e9 pour permettre d\u2019\u00e9crire des documents hypertextuels, en\u00a0reliant les diff\u00e9rents\u00a0documents\u00a0d\u2019internet avec des hyperliens.\u00a0\u00a0<\/span><\/p>\n

\u00a0<\/span>Aujourd\u2019hui, ces documents sont appel\u00e9s\u202f\u00ab\u202fpage web\u202f\u00bb.\u00a0<\/span><\/p>\n

\u00a0<\/span>Voici un exemple de page que j\u2019ai \u00e9crite au d\u00e9but de mon parcours dans l\u2019entreprise \u00ab\u202fWeb\u00a0Development\u202f\u00bb.\u00a0<\/span>\n\n\u00a0<\/span><!DOCTYPE html>\u00a0\u00a0\n<\/span>\n<html>\u00a0<\/span>\n<head>\u00a0<\/span>\n<title>Test_2017<\/title>\u00a0<\/span>\n<meta\u00a0charset=\"utf-8\">\u00a0<\/span>\n<\/head>\u00a0<\/span>\n<body>\u00a0<\/span>\n<font>Test de ce site web<\/font>\u00a0<\/span>\n\u00a0<audio\u00a0src=\"DJ_Snake.mp3\" type=\"audio\/mp3\"\u00a0controls>\u00a0<\/span>\n<img\u00a0src=\"images.jpeg\">\u00a0\u00a0<\/span>\n\u00a0<\/body>\u00a0<\/span>\n\u00a0<\/html>\u00a0<\/span><\/pre>\n
\u00a0<\/span>Je n’ai pas pu colorier\u00a0le code\u00a0car ce n’est pas un langage pour \u00e9crire des programmes\u00a0mais pour \u00e9crire des pages web.\u00a0<\/span><\/p>\n
Le navigateur web (chrome par exemple) va d\u00e9coder le HTML pour le rendre visible sur l’\u00e9cran\u00a0<\/span><\/p>\n
Voici le r\u00e9sultat de ce code :\u00a0<\/span><\/p>\n

Java Script\u202f:\u00a0<\/span><\/h1>\n
\u00a0<\/span>Java Script est utilis\u00e9\u00a0pour cr\u00e9er des sites web mais aussi pour les serveurs.\u00a0<\/span><\/p>\n
Java script a \u00e9t\u00e9 cr\u00e9\u00e9 en mai 1995 par Brendan Eich pour Netscape Communication Corporation. Le langage est une simplification de Java pour les d\u00e9butants.\u00a0<\/span><\/p>\n
Brendan Eich a aussi cod\u00e9 Live Script. Live script est Java script sauf pour les diff\u00e9rents serveurs.\u00a0<\/span><\/p>\n
En\u00a0d\u00e9cembre 1995 Netscape annonce\u00a0la sortie de Java Script.\u00a0<\/span><\/p>\n
Plus tard Microsoft utilisa Java Script pour faire leur site web.\u00a0<\/span><\/p>\n
