❌ ✈️ How to cancel Javascript API request with AbortController

The fetch API in JavaScript allows making HTTP requests, working with promises for request completion.
For real-time suggestions in a search bar, fetch requests are made as the user types.
Repeated fetch requests can be inefficient when multiple requests are made for each typed character.
Using a debounce function delays fetch requests until the user stops typing.
Even with debounce, there can be issues if the user types quickly after the delay.
AbortController in modern browsers allows canceling requests before completion.
An example is shown with an input field to search for posts, canceling previous requests if new ones are made.
AbortController helps improve performance by canceling ongoing requests to prevent unnecessary API calls.
