Developer’s glossary

By Jean-François Sauriol

You are dealing with an agency that is developing your website, but you don’t understand why they are talking to you about sprints?

You want to hire a web developer for your company, but you don’t understand the languages listed on their CV. Are all developers polyglots?

Your friend is a web developer, and you’d like to know why they care more about their CSS style than their fashion style?

You share all our articles out of solidarity, but you don’t understand what we’re talking about? I understand you. A developer’s vocabulary can sometimes seem obscure to a newcomer. Don’t panic anymore. I’ve prepared a small glossary to make your communications with developers easier.
