how do I do that?

const favoriteCities = function() {
    const output = document.getElementById("output");
    output.innerHTML = "";
    
    const input = document.getElementsByName("favoriteCities[]");
    for (let i = 0; i < input.length; i++) {
        const div = document.createElement("div");
        div.innerText = `City #${i + 1} is ${input[i].value}`;
        output.appendChild(div);
    }
};

- The function does not need an input parameter, unless you want to pass it a random number. Assuming yo do not, then generate the number as the first step.
- The if statements only need to be as follows
- 1: If the value is less than 10 set colorCode to "green"
- 2: Else If it is less than 50 set colorCode to "yellow" (we already know it is not less than 10)
- 3: Else set it to "blue" (it must be 50 or greater)
- return colorCode to the caller of the function.

function colorSelector (colorCode) {

let randomNumber = Math.floor((Math.random() * 100));

if (randomNumber < 10) {
    console.log("green");
}

else if (randomNumber >= 10 && randomNumber < 19) {
    console.log("yellow");
}

else if (randomNumber > 19) {
    console.log("blue");
}


return (randomNumber);


}

console.log(colorSelector(50));

I know that I have to use the Math.floor and Math.random to create a random number and the if and return operators but I think im messing up the order. Please help anyone.

else if (randomNumber >= 10 && randomNumber < 19) {
         ^^^^^^^^^^^^^^^^^^

else if (randomNumber > 19) {

And it this point it must be > 19, so all that is needed is a simple else clause.
