Quick definition · 2 min Coding term
Dependency
A dependency is a package your project relies on to work. If it is missing, your app breaks.
Think of it like
Ingredients a recipe needs. No eggs, no cake. Your project depends on them being present.
Example
Your app lists its dependencies so anyone can install the exact packages it needs to run.
Why it matters
Dependency errors are among the most common things beginners hit. Knowing the word demystifies half of them.
