Sending data to the server outside JSON

Hi Serdar,

For you first question; Why We Send Data in JSON Format to the Backend

1. Readability and Ease of Use:

2. Compatibility:

3. Lightweight:

4. Native to JavaScript:

Other Ways to Send Data to the Backend and How Data Was Sent Before JSON

Before JSON became the standard, data was often sent in:

1. XML (Extensible Markup Language):

Example:  John 30

2. Form-urlencoded:

Example: name=John&age=30

3. Plain Text

4. Binary Formats:

• Protocol Buffers (Protobuf)
• MessagePack

5. CSV (Comma-Separated Values)

6. YAML (YAML Ain't Markup Language)

For Answer to your Question 2

1. JSON.parse:

• Usage:

  let jsonString = '{"name": "John", "age": 30}'; let obj = JSON.parse(jsonString); console.log(obj.name); // John

2. jQuery.parseJSON:

• Usage:

let jsonString = '{"name": "John", "age": 30}'; let obj = jQuery.parseJSON(jsonString); console.log(obj.name); // John

Which Function to Use?

• Use JSON.parse: Given that all modern browsers support JSON.parse, it is the preferred method. It is a native function, faster, and does not require loading the jQuery library.
• Avoid jQuery.parseJSON: Unless you are maintaining very old legacy code that specifically relies on jQuery for JSON parsing, you should avoid using jQuery.parseJSON.

Hope you find this helpful. :)
