Underscore vs axios: What are the differences?
Underscore is a utility library for JavaScript that provides a wide range of functions to facilitate common programming tasks. Axios is a promise-based HTTP client for the browser and Node.js. Below are the key differences between Underscore and Axios.
1. **Functionality**:
Underscore primarily focuses on providing utility functions for manipulating arrays, objects, and functions, while Axios specializes in making HTTP requests using promises.
2. **Dependencies**:
Underscore has no dependencies and can be used independently in projects, whereas Axios requires the use of a Promise polyfill for older browsers.
3. **Common Usage**:
Underscore is commonly used for tasks like filtering data, mapping arrays, and handling collections, while axios is utilized for sending HTTP requests, handling responses, and managing API interactions.
4. **Browser Compatibility**:
Underscore is designed to work across different browsers and environments without any compatibility issues, while Axios is specifically optimized for making HTTP requests in the browser and Node.js.
5. **Type of Library**:
Underscore is more of a general-purpose utility library that covers a wide range of programming tasks, while Axios is focused solely on facilitating HTTP communications.
6. **Asynchronous Operations**:
Axios simplifies handling asynchronous operations by using promises, allowing for cleaner and more organized code compared to Underscore, which deals more with synchronous operations.
In Summary, Underscore is a general-purpose utility library, whereas Axios specializes in making HTTP requests using promises, providing a more focused approach for handling API interactions.
