Ruby, un langage accessible<\/h3>

<\/div>
Une des premi\u00e8res choses agr\u00e9ables avec Ruby on Rails repose sur le langage Ruby<\/a> en lui-m\u00eame. La syntaxe est simple, peu verbeuse, proche de la langue anglaise et tr\u00e8s souple. Pour les d\u00e9veloppeurs chevron\u00e9s, Ruby ouvre la voie \u00e0 la meta-programmation<\/em> (le fait d'\u00e9crire du code pour que votre service g\u00e9n\u00e8re d'autres morceaux de code automatiquement) de mani\u00e8re unique. Intellectuellement, c\u2019est un plaisir de structurer sa pens\u00e9e et d'\u00e9crire du code dans ce langage.

<\/div>

Un tool set minimal<\/h3>

<\/div>
Une fois le setup<\/a> et la config<\/a> de votre machine r\u00e9alis\u00e9s, le tool set<\/em> associ\u00e9 \u00e0 Ruby on Rails est le plus simple qui soit : un \u00e9diteur de texte, un terminal et un navigateur. Aucun temps et \u00e9cran de chargement lorsque vous codez. Votre ordi respire. Vous aussi.

<\/div>

Une flexibilit\u00e9 extraordinaire<\/h3>

<\/div>
Rails est un framework<\/em>, c'est-\u00e0-dire un cadre dans lequel le d\u00e9veloppeur doit s'inscrire. Il s\u2019agit \u00e9galement d\u2019un outil unique et parfaitement adapt\u00e9 aux d\u00e9veloppements d'applications web. Pour une startup, aller vite, pivoter, it\u00e9rer, changer d\u2019avis, scaler, faire et d\u00e9faire fait partie du quotidien. Rails offre une flexibilit\u00e9 extraordinaire pour encaisser sans broncher tous ces changements.

<\/div>
Quel que soit le domaine dans lequel vous souhaitez vous investir, votre besoin sera g\u00e9n\u00e9ralement le suivant : une base de donn\u00e9es, un front-end<\/a> (la partie visible de votre application) et un back-end<\/a> (le code c\u00f4t\u00e9 serveur). La r\u00e9unification et l\u2019agencement sans douleur de ces trois \u00e9l\u00e9ments sont d\u00e9finitivement le sweet spot<\/em> de Rails.

<\/div>

Un apprentissage et une collaboration simplifi\u00e9s<\/h3>

<\/div>
Rails repose sur le principe de Convention over Configuration<\/em><\/a>. L'architecture des dossiers de votre code est normalis\u00e9e, et rendue obligatoire par le framework. Il existe donc le rails way<\/em>. Ce dernier permet \u00e0 un d\u00e9veloppeur Rails de prendre en main en seulement quelques heures n'importe quelle application Rails, m\u00eame s'il n'en a pas cod\u00e9 une ligne, et ainsi d\u2019en faciliter la collaboration et l\u2019apprentissage.

<\/div>
Cet aspect peut d\u00e9contenancer les d\u00e9veloppeurs venant d'un langage plus verbeux, qui vont souvent se demander o\u00f9 se trouve le code. Il faut se faire \u00e0 cette abstraction. Une fois les conventions comprises et assimil\u00e9es, la vitesse de d\u00e9veloppement d'une nouvelle fonctionnalit\u00e9 est alors extraordinaire.

<\/div>

La force de sa communaut\u00e9<\/h3>

<\/div>
Rails est une Gem<\/em><\/a>, c'est-\u00e0-dire un module open source, d\u00e9velopp\u00e9e et maintenue depuis plus de 10 ans par des milliers de d\u00e9veloppeurs<\/a>. Il existe en suppl\u00e9ment des milliers de gems<\/em><\/a>, d'ailleurs nous vous en avions pr\u00e9sent\u00e9 25 r\u00e9cemment<\/a>. Ainsi, lorsqu'une nouvelle fonctionnalit\u00e9 est \u00e0 d\u00e9velopper, dans 90% des cas le travail peut \u00eatre r\u00e9alis\u00e9 rapidement en se basant sur un module existant.

<\/div>
Le code de chaque gem se trouve sur GitHub, s'il manque quelque chose, aucun souci, il suffit de forker<\/em> et d'ajouter soi-m\u00eame la fonctionnalit\u00e9 pour son propre produit. Libre \u00e0 vous d\u2019ensuite faire une pull request<\/em> au projet initial pour partager ce d\u00e9veloppement avec la communaut\u00e9 (give back). Cet esprit est formidable, sur le plan \u00e9thique \/ moral, mais aussi \u00e9conomique, car les d\u00e9veloppeurs ruby ne r\u00e9inventent pas la roue et int\u00e8grent au mieux ces briques<\/em> existantes afin de se concentrer sur les besoins business<\/strong> des utilisateurs \/ clients.

<\/div>
Depuis toujours, la communaut\u00e9 Ruby repose sur une culture d'ouverture et de partage. En suppl\u00e9ment des multiples communaut\u00e9s sur le web, vous trouverez de nombreux relais physiques partout dans le monde, \u00e0 l'image de l'excellent groupe Paris.rb<\/a>.

Une skill reconnue dans le milieu Startup\u2026<\/h3>

<\/div>
Si il est vrai que dans le monde corporate<\/em> des langages comme Java et C# restent les rois, Ruby de son c\u00f4t\u00e9 est souvent pl\u00e9biscit\u00e9 par le milieu startup. De nombreuses startups devenues de grand succ\u00e8s du web ont commenc\u00e9 et continuent avec Rails (GitHub, Twitter, AirBnB, Shopify, Coinbase, Instacart, Kickstarter\u2026) et quelques alumni du Wagon ont d\u2019ailleurs trouv\u00e9 des postes de junior developer<\/a> \u00e0 Paris.

\u2026qui fait sens au sein d\u2019une stack plus large<\/h3>

<\/div>
Pourquoi existe-t-il autant de langages de programmation diff\u00e9rents ? Ne serait-il pas plus simple d'en avoir qu'un seul \u00e0 apprendre ? Il y a beaucoup de raisons, notamment historiques, qui peuvent expliquer cette multitude de langages. Il y a des langages qui vont \u00eatre plus adapt\u00e9s pour faire du web, d'autres pour faire du mobile ou encore d'autres pour envoyer un homme sur Mars. Ce qui est int\u00e9ressant de noter, c'est que les briques \u00e9l\u00e9mentaires de tous ces langages sont tr\u00e8s proches, voire identiques. Une fois qu'on ma\u00eetrise un langage de programmation, il est beaucoup plus ais\u00e9 d'en apprendre un second. Le plus dur reste d'acqu\u00e9rir le mindset<\/em> de programmeur.

<\/div>
Par la suite, si un job vous demande de coder dans un autre langage, apr\u00e8s une semaine intensive \u00e0 fond dessus vous ferez rapidement l'analogie syntaxique entre votre langage pr\u00e9f\u00e9r\u00e9 et le nouveau. Dans les faits il vous faudra au minimum ma\u00eetriser une stack plus compl\u00e8te :
