Javascript : loop in conditional based on array [duplicate]

Question

I would like to check multiple conditions based on an extensible array of variables. What's the method to check them ?

For example:

a = 0;
b = 1;
c = 0;

if (a == 0 && b == 0 && c == 0) {
    console.log("all a,b,c variables == 0")
}

Good. Now for an array ?

arr = ["a", "b", "c", "d", ...];

if (for i = 0; i < arr.length; i ++ { arr[i] == 0 && }) {
    console.log("all arr variables == 0")
}

I think I'm going the wrong way here... Is there a solution check a lot of statements based on an array ?

Thank you for your help.

"I think I'm going the wrong way here..." Since your code has syntax errors, definitely yes. What exactly are you trying to achieve? "Is there a solution check a lot of statements based on an array ?" What exactly does that mean? — Felix Kling

const array = [0, 0, 0];
array.every(x => x === 0); // true
