Don't shit on JS if you don't know JS. Here's how to do it properly:

Array.prototype.avr = function() {
return (()=>{
let c = 0;
for (i=0;i<this.length;i++){
c+=this[i];
}
return c/this.length;
})();
}

const list = [1, 2, 3, 4, 5, 9, 10];
console.log(list.avr());

Although, you do have a point. Couldn't even use a lambda function as prototype for some reason, had to return an anonymous function for no reason. Anyone know why lambda functions aren't supported in prototypes?
