What is JSON?🤔
JSON (JavaScript Object Notation) is a lightweight data-interchange format.
JSON is easy for humans to read and write, yet it is efficient enough for computers to handle.
JSON is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, or passing state information between the two) and for serializing structured data into a string representation.
It can be used to represent numbers, strings, booleans, arrays, objects, and raw bytes in a standardized way.
JSON is often used to output data in the Web API's response body.
Advantages of using JSON
JSON is an open standard that enables data to be exchanged between applications without the need for a middleman.
JSON is easy for humans to read and write, which makes it ideal for data exchange between different applications.
JSON is more compact than XML, and therefore easier to transmit.
It is supported by all programming languages.
It can be used on all platforms.
It is a light weight database standard, so data transmission is fast.
