What does "stateless" mean in programming?
stateless is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A design where each request contains all the information needed to process it, and the server does not store any memory of previous requests. Stateless services are easier to scale horizontally because any server can handle any request. REST APIs are designed to be stateless.
Example
"Our API is stateless: the JWT in each request carries all the auth info the server needs."
