Promise.all(): Wait for Multiple Promises at Once
Promise.all() runs multiple promises in parallel, resolving only when all have succeeded. It's for when you need data from several API endpoints to render a single component.
Promise.all() takes an array of promises and returns a new promise that resolves only when every input promise has resolved. The result is an array of values in their original order. It's ideal for aggregating data from multiple API endpoints before rendering a UI component that depends on all of them. The main footgun is its fail-fast behavior: if any single promise rejects, the entire operation rejects immediately, discarding results from any promises that already succeeded.
