What is Test-Driven Development in JavaScript?

Test-Driven Development (TDD) is a software development process where you write tests before writing the actual code. In JavaScript, this means you create unit tests using frameworks like Jest or Mocha to define how your code should behave.

Can you explain the steps involved in TDD?

Sure! The TDD process typically involves three main steps: 1) Write a failing test for a new feature, 2) Write the minimum code necessary to pass the test, and 3) Refactor the code while ensuring all tests still pass.

What are the benefits of using TDD?

Some benefits of TDD include improved code quality, easier debugging, and better design decisions. It also helps ensure that your code meets the requirements from the start.

Are there any drawbacks to TDD?

Yes, some drawbacks include the initial time investment to write tests, the potential for over-testing, and the learning curve for developers new to TDD.
