Array type notations: <code>T[]</code> vs. <code>Array&lt;T&gt;</code> in TypeScript

Read Original

This article explores the two equivalent notations for Arrays in TypeScript: T[] and Array<T>. It explains why TypeScript prefers T[] (historical reasons) and why the author prefers Array<T> (better readability for complex types, consistency with other generic types, and avoiding confusion with tuples). The post also covers syntactic caveats and practical examples.
