[removed] remove event listener

Question

I\'m trying to remove an event listener inside of a listener definition:

canvas.addEventListener(\'click\', function(event) {
    click++;
    if(click == 50         


        

Answer 1

You could use a named function expression (in this case the function is named abc), like so:

let click = 0;
canvas.addEventListener('click', function abc(event) {
    click++;
    if (click >= 50) {
        // remove event listener function `abc`
        canvas.removeEventListener('click', abc);
    }
    // More code here ...
}
