What are the key differences between Yarn and NPM?

Yarn and NPM are both package managers for JavaScript, but they have some key differences. Yarn is known for its speed and reliability due to its caching mechanism and parallel installation process, while NPM has improved its performance in recent versions. Yarn also uses a lockfile to ensure consistent installs across environments.

Can you explain the caching mechanism in Yarn?

Sure! Yarn caches every package it downloads, so if you install the same package again, it can retrieve it from the cache instead of downloading it again. This significantly speeds up the installation process.

What about the security features of both?

Yarn has a feature called 'yarn audit' that checks for vulnerabilities in your dependencies. NPM also has a similar feature, allowing you to run 'npm audit' to identify and fix security issues in your packages.

Which one should I use for my project?

It depends on your project's needs. If you prioritize speed and reliability, Yarn might be the better choice. However, if you prefer a more widely adopted tool with extensive community support, NPM is a solid option.
