javascript file:

var danger = 1;
var safe = 2;

function stepLeft() {
    if (danger == 1) {
        alert("STOP!")
    } else {
        alert("START!")
    }
}

Nothing is happening when I try this. No error message in console either. (the script is linked properly in html).

You only defined the function, but you actually never ran it. Try adding 

stepLeft();

After the definition to execute it.
