Fluent Interface
In plain terms
An API design enabling readable, chainable method calls.
Going deeper
A fluent interface lets you chain methods that each return the object, producing readable, sentence-like code. Calls flow naturally one after another.
Under the hood
Common in builders and query DSLs; improves readability but can complicate debugging.
Examples
Builders, LINQ, jQuery chaining, query DSLs, configuration APIs.
Think of it like...
Like giving directions in one flowing sentence rather than choppy separate commands.
