So, what exactly are build tools? They are a suite of utilities designed to automate repetitive tasks, enhance code efficiency, and enhance your development process. These build tools typically fall into three primary categories: task runners, bundlers, and compilers.

Task runners are specialised tools that automate mundane, recurring tasks like code testing, code linting, and code minification. Bundlers empower developers to consolidate multiple files into a single file. Which not only reduces loading times but also boosts overall performance. Compilers, on the other hand, enable developers to write code in one language and compile it into another. For example, utilising TypeScript to create JavaScript code.

Leveraging build tools offers a multitude of advantages for enhancing the development workflow. Including time savings, code quality improvement, and simplification of the deployment process. These tools automate repetitive chores, enhance code quality. And provide immediate feedback on errors and code standards, ultimately enhancing the developer experience and mitigating development-related stress.
