For loop spamming false in javascript

I’m trying to write a code where if a randomly generated number matches one of the numbers in for loop it should output "True" if not then false.

let min = 20;let max = 50;

let a = (Math.floor(Math.random() * (max - min)) + min);

for (let i=0; i<30; i++){
    if (i == a){
        console.log("True");
        break;
    }
    else{
        console.log("False");
    }
}

It ends up spamming false until the point it reaches the condition. Is there a way I can prevent this?

    If I correctly understand, the best thing to do (well, a good thing at least) is to take the logging out of the loop entirely:

    let min = 20;let max = 50;

let a = (Math.floor(Math.random() * (max - min)) + min);
let message = "False";
for (let i=0; i<30; i++){
    if (i == a){
        message = "True";
        break;
    }
}
console.log(message);

    And you could do that with a couple of different approaches, but the basic idea is that your code remembers what happened in the loop, and then reports that after the loop is finished.

    it’s generate a random number between 20 – 50 ,

    but your loop is stop at 30 ,
    you might fix it by edit your loop end point to 50

    for (let i=0; i<=50; i++){
    if (i == a){
        console.log("True");
        break;
    }
    else{
        console.log("False");
    }
}

    now it works !
