Frequently Asked Questions
What is the difference between a library and a framework?
A library provides specific functions you call when needed, like a toolbox you dip into. A framework provides the overall structure and calls your code. You use a library; a framework uses you. Both speed up development.
Are JavaScript libraries safe to use?
Reputable, well-maintained libraries from trusted sources are generally safe. The risk comes from using outdated or abandoned libraries with known vulnerabilities. Your developer should keep dependencies updated as part of regular maintenance.
Does using libraries make my site slower?
It can if too many are loaded or if large libraries are used for small tasks. Good developers choose lightweight libraries and only include what's actually needed. Modern techniques like tree shaking help remove unused code.
