I have a simple app that counts repeating numbers inside of an array. Users enter numbers through prompt (i.e. 2, 1, 2, 2).
And when I want to output the result (which is an object) through document.write() function I get: [object Object]
When I output it through console I get the result I expect: Object {2: 3, 1:1}
Down below is html and js, and Plunkr can be found here
I would like the results of the object to be written on the page...

- You can't. Because HTML itself can't parse objects. You can serialize it to a string though. – Red Commented Sep 4, 2017 at 11:37
- I tried using String(counts) but it didn't work. JSON.stringify(counts) did the trick however. Thanks a bunch you guys. – prius Commented Sep 4, 2017 at 11:47

string(counts)(does that function even exist?) is wrong.JSON.stringifyis correct. See my awnser with the fiddle. – Red Commented Sep 4, 2017 at 11:47 - Well, probably not :)... Yup.. I did it your way and it works beautifully.. Thanks – prius Commented Sep 4, 2017 at 19:11

Reset to default 1You can't. HTML can't parse objects. You can however convert the object to a string
$(document).ready(function(){
var n = prompt("Enter your numbers").split(",");
console.log(n);
var counts = {};
n.forEach(function(x){
counts[x] = (counts[x] || 0) +1;
});
console.log(counts);
document.write(
"<h1>Enter numbers when prompted!</h1>" +
"<p>You entered following numbers:</p>" + JSON.stringify(n) + "<br/>" +
"<p>The occurence is as follows:</p>" + JSON.stringify(counts));

<div id="content"></div>Use JSON.stringify(counts) to serialize you object and you can print it in the HTML
document.write(
"<h1>Enter numbers when prompted!</h1>" +
"<p>You entered following numbers:</p>" + n + "<br/>" +
"<p>The occurence is as follows:</p>" + JSON.stringify(counts));
});
