What does "ellipsis" mean in programming?
ellipsis 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
The ... character sequence. In English prose it indicates omitted text. In JavaScript and TypeScript it is the spread operator (expands an array) and the rest operator (collects remaining arguments).
Example
"const merged = [...arr1, ...arr2]; // spread operator merges two arrays"
