What is json. And what is node.js

Question

what?

Answer 1

JSON is a format that is used between applications in order to send and retrieve data.If you want to fetch weather data from a weather API the weather API will send all the informations in JSON.Look at the example below :

{
"City":"New York",
"temperature":100,
"humidity":60
}
note that values are separated with coma.

If you decide to make a web app you can use node.js to handle backend(request,database updates) operations in javascript.
You can alternatively use php but as far as i konw php uses mutli-threading strategy
which is not efficent as node.js because it has a event driven architecture

age : 27,
name : “solo”,
address : {
