JAVASCRIPT

how to do addition in javascript

//To add in Java script, you have to put an additon symbol '+' between them. If you have stored two numbers in variables, just put an addition symbol between the variable names.
//For example:
var a = 5
var b = 6
var c = a+b
var d = 5+6

Bot.send (c)/ print (c)// or whatever you use to get output
Bot.send (d)/ print (d)// or whatever you use to get output

//output will be: 11, 11

javascript addition example

//create XMLHttpRequest object
const xhr = new XMLHttpRequest()
//open a get request with the remote server URL
xhr.open("GET", "https://world.openfoodfacts.org/category/pastas/1.json")
//send the Http request
xhr.send()

//EVENT HANDLERS

//triggered when the response is completed
xhr.onload = function() {
  if (xhr.status === 200) {
    //parse JSON datax`x
    data = JSON.parse(xhr.responseText)
    console.log(data.count)
    console.log(data.products)
  } else if (xhr.status === 404) {
    console.log("No records found")
  }
}

//triggered when a network-level error occurs with the request
xhr.onerror = function() {
  console.log("Network error occurred")
}

//triggered periodically as the client receives data
//used to monitor the progress of the request
xhr.onprogress = function(e) {
  if (e.lengthComputable) {
    console.log(`${e.loaded} B of ${e.total} B loaded!`)
  } else {
    console.log(`${e.loaded} B loaded!`)
  }
}
