Random Function in JavaScript

Question

How do I generate a random function in JavaScript?

Answer 1

Math.random() returns a random number between 0 (inclusive),  and 1 (exclusive).

Math.random() used with Math.floor() can be used to return random integers.

For example
Math.floor(Math.random() * 10);
Returns random integer from 0 to 9

Answer 2

f_arr = [add1 ,add2 ,add3 ,add4 ,add5 ,add6 ,add7 ,add8 ,add9 ];

function comp(){
if(f_arr.length > 0){
var i = Math.floor(Math.random()*f_arr.length);

f_arr[i]();

}
}

Math.floor(Math.random() * 1000000000); //generates a 9 digit random number

YCS-Venom Movement can be const. Three options: Left, up and down.
