// An empty array
var listOfCountryCodes = []
console.log(itsthere(listOfCountryCodes)) // false

// Remains true as long there is something in the array regardless of data type
var listOfCountryCodes = ['UK', 'SG', ' ', null]
console.log(itsthere(listOfCountryCodes)) // true

Object

// An empty object
var personInfo = {}
console.log(itsthere(personInfo)) // false

Why use itsthere?

const itsthere = require('itsthere')

const randomHash = "0424974c68530290458c8d58674e2637f65abc127057957d7b3acbd24c208f93"

// Typical checking for null and undefined and empty strings
if (randomHash !== null || randomHash !== undefined || randomHash !== "") {
    console.log("accepted") // accepted
}
else{
    console.log("reject")
}

// A much shorter and easier alternative compared to the above
if (itsthere(randomHash)) {
    console.log("accepted") // accepted
}
else{
    console.log("reject")
}
