How to use fetch to send data (POST Request)

How to use fetch to send data (POST Request)
🔹 What it means:

fetch() can not only get data but also send data to a server — for example when:

submitting a form,

creating an account,

logging in,

posting a comment.

This is done with a POST request.

🔸 Example in JavaScript:
fetch("https:api.example.com/users",
method: "POST",
headers:
"Content-Type": "application/json"

body: JSON.stringify(
name: "Anna",
age: 25

.then(response = response.json())
.then(data = console.log("Server response:", data))
.catch(error = console.error("Something went wrong:", error));

🔹 Step-by-step:

We tell fetch where to send the request.

We specify method: "POST".

We add headers (to tell the server we’re sending JSON).

We put our data inside body as JSON text.

We wait for the server to respond.

🔹 Example response:
"status": "success",
"message": "User Anna added successfully!"

💡 In short:
Term Meaning
fetch() Sends or gets data from a server
method: "POST" Used when sending data
headers Describe the type of data sent
body The actual data you’re sending
JSON.stringify() Turns an object into text for sending
