P5 javascript LoadJSON Data is to late

Question

I've tried to read a Json file with loadJSON from p5 but the data comes to late. If I try console.log(JSON.stringify(data)) it says {}.

function setup() {
    for(i = 0;i <= 3;i++) {

        //load the JSON
        data = loadJSON('test'+ i +'.json');

        //Work with it
        console.log(JSON.stringify(data);
   }
}

_"This method is **asynchronous**, meaning it may **not finish** before the **next** line in your sketch is executed..."_ ([Reference](http://p5js.org/reference/#/p5/loadJSON)) - You need to read the docs and use a callback function as explained in the duplicate — Alon Eitan, Dec 02 '18 at 10:15
Ds = loadJSON('test' + 1 + '.json'); delay().then(function(tt){ console.log(Ds); console.log(date); }) Dosn't work in a loop?! — MrMugame, Dec 02 '18 at 12:21

function test(mynewdata) {
    console.log(mynewdata);
}

data = loadJSON('test' + i + '.json',test);

This works for me. Thanks!
