Promises vs Callbacks

Developers should learn Promises to write more maintainable and readable asynchronous code, especially in web development for handling API calls, file I/O, or timers meets developers should learn callbacks to manage asynchronous tasks effectively, such as handling api responses, file operations, or ui events in web development. Here's our take.

Promises

Nice Pick

Developers should learn Promises to write more maintainable and readable asynchronous code, especially in web development for handling API calls, file I/O, or timers

Pros

• They are essential in JavaScript for avoiding 'callback hell' and are widely used in modern frameworks like React and Node
• Related to: async-await, javascript

Cons

• Specific tradeoffs depend on your use case

Callbacks

Developers should learn callbacks to manage asynchronous tasks effectively, such as handling API responses, file operations, or UI events in web development

Pros

• They are essential in environments where blocking operations would degrade performance, like in Node
• Related to: javascript, asynchronous-programming

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Promises if: You want they are essential in javascript for avoiding 'callback hell' and are widely used in modern frameworks like react and node and can live with specific tradeoffs depend on your use case.

Use Callbacks if: You prioritize they are essential in environments where blocking operations would degrade performance, like in node over what Promises offers.

The Bottom Line

Promises wins

Developers should learn Promises to write more maintainable and readable asynchronous code, especially in web development for handling API calls, file I/O, or timers
