Course of Linting in JavaScript and TypeScript

💸 First lesson available without registration 💸

In teamwork, it is essential to make a series of decisions about how we are going to develop our code. They range from the most mundane (whether we use tabs or spaces, line width…) to decisions about how we organize our code.
ESLint is a tool that can greatly facilitate the task of ensuring that our code meets the standards we have decided as a team. In this course, we will see how to take ESLint much further than stylistic considerations and how it can help us avoid bugs and improve the architecture of our application.
