Differences Between Fetch and Axios

Fetch and Axios are two widely used HTTP request tools in frontend development. Here’s a detailed comparison:

1. Origin & Compatibility

🚀 Fetch:

• Native browser API (part of Web Standards) with no installation required.
• Compatibility: Works in modern browsers but not in IE (requires polyfills like whatwg-fetch).

🚀 Axios:

• Third-party library (built on `XMLHttpRequest`) requiring installation via npm or CDN.
• Compatibility: Supports older browsers, including IE 11.

2. Request & Response Handling

🚀 Fetch:

• Manual JSON parsing: Requires explicit .json() method to parse responses.
• No automatic error handling for HTTP errors (e.g., 404/500). Developers must check `response.ok`.
• Cookies: Requires manual configuration with credentials: ‘include’.

const options = {
  method: "POST",
  headers: {
    Accept: "application/json",
    "Content-Type": "application/json;charset=UTF-8",
  },
  body: JSON.stringify({ a: 10, b: 20 }),
};
fetch(url, options)
  .then(response => {
    if (!response.ok) throw new Error("HTTP error");
    return response.json()…
