How do I make my JavaScript loop run slower [duplicate]

Question

I am trying a little bit of coding and I would like for the 30 character strings to appear in the 1 second intervals one after another when the code is started. I tried setInterval & setTimeout and I couldn't get it to work. If someone could please help that would be much appreciated.

count = 0
while (count < 200) {
    console.log(create_random_string(30))

function create_random_string(string_length){
    var random_string = '';
    var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz'
    for(var i, i = 0; i < characters.length; i++){
        random_string += characters.charAt(Math.floor(Math.random() * characters.length))
    }
    return  "|BTC| " + random_string +  "  | " + " PRIVATNI KLJUČ NIJE ISPRAVAN" + "  | " + " STANJE: 0.00"
}
count = count + 1
}

setInterval(code, time); 

this function will allow you to wait X miliseconds before running the code defined.

here, the correct code, and i fixed your formatting a bit.

let count = 0;
while (count < 200) {
    setTimeout(
        function() { console.log(create_random_string(30)); }
        , 500);
    count++;
}

function create_random_string(string_length){
    var random_string = '';
    var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz'
    for(var i, i = 0; i < characters.length; i++){
        random_string += characters.charAt(Math.floor(Math.random() * characters.length))
    }
    return  "|BTC| " + random_string +  "  | " + " PRIVATNI KLJU? NIJE ISPRAVAN" + "  | " + " STANJE: 0.00"
}

by the way, you probably wanted to replace characters.length inside your for loop for : string_length to use the fuction's parameter (which you never actually used)
