This section, we'll focus on two important aspects of JavaScript development.

  • Test-driven development: We'll write automated tests before writing our code.
  • Modern development environments: We'll create an environment that will make it easier to incorporate JavaScript libraries and scaffold large projects.

We will use Jest, a tool for writing coded, automated tests. We'll learn about module bundling with webpack to keep our code base well-organized and efficient and we'll incorporate tools that help us do other tasks like linting, which we can use to quickly spot errors.

Finally, we'll learn about JavaScript features from ES6 such as new ways to declare JavaScript variables, classes, modules, and more.

Independent Project Objectives

This section's project will be reviewed for the following objectives:

  • Business logic has 100% line coverage with Jest.
  • Each spec was committed before writing its corresponding code.
  • Project utilizes classes, a feature of ES6.
  • Dependencies are managed with npm.
  • webpack is used to lint, bundle, and process code.
  • Project is in a polished, portfolio-quality state.
  • Project demonstrates understanding of section's concepts. If prompted, you are able to discuss your code with an instructor using correct terminology.
