how to make two variables share a math.random value in javascript

Suceeded in randomizing a quote but now the values name and quote don't match, is there a way to make json.name and json.quote share the same random value? so Einstein's quote isn't matched with the name Nightingale.

let url =;

$.getJSON( url, function( json ) {

let rand = function getRandom() {
return Math.floor(Math.random() * 4) + 1  ;
}

//console.log(rand());

document.write(" "" + json[rand()].quote +""" + "  by " 
+json[rand()].name );


});

document.write(" "" + json[rand()].quote +""" + "  by " 
+json[rand()].name );

everytime you use rand(), it will generate a different number, so json[rand()].quote and json[rand()].name will be different because you are using different keys, so save rand() in a variable first and then use it, like:

var randNumber = rand();
document.write(" "" + json[randNumber].quote +""" + "  by " +json[randNumber].name );
