Fetch API & Handling JSON Responses

Which request option affects how the browser handles CORS?

fetch('/api/data', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Custom-Header': 'value'
  },
  body: JSON.stringify(data),
  mode: 'cors',
  cache: 'no-cache',
  redirect: 'follow'
})

cache
mode
The mode option controls CORS behavior: 1) 'cors' enables cross-origin requests, 2) Affects what headers can be sent/received, 3) Determines server requirements for CORS headers, 4) Essential for cross-origin API interactions, 5) Other modes include 'same-origin' and 'no-cors', 6) Critical for security in web applications.
