JavaScript: How to create a function that receives an array of numbers and returns an array containing only the positive numbers?

What is Wrong with this Code? I should create a function that receives an array of numbers and returns an array containing only the positive numbers. How can it be modified? Especially Modified. Not another code!

all = prompt("Give me an array of numbers seperated by ','");

var splitted = all.split`,`.map(x=>+x);
function returner(splitted){
    var positive = [];

for(var i = 0; i < splitted.length; i++);{
    var el = splitted[i];
    if (el >= 0){
        positive.push(el);
    }
    
}
return positive;
}

var positive = returner(splitted);
print(positive);

First I noticed that you are using print to check your output - that should be console.log(). But your real mistake is the semicolon after the for bracket in line 7.

Here is a working code-snippet:

let all = prompt("Give me an array of numbers seperated by ','");

let splitted = all.split`,`.map(x => +x);
function returner(splitted) {
    let positive = [];

    for (let i = 0; i < splitted.length; i++) {
        const el = splitted[i];
        if (el >= 0) {
            positive.push(el);
        }
    }

    return positive;
}

var positive = returner(splitted);
console.log(positive);
