Question

how do i test this javascript function 

showing it working would be amazing!!!!

the function and instructions are as follows

function repeatf(f,n) {
    if(n<=0) {return "";}
    var result= new Array(n);
    for(var i=0; i<n; i++) {
        result[i]=  f();
    }
    return result;
}

repeatf( f, n )

This function accepts a function of no arguments ( f ) and an integer number ( n ). The function must return a list that contains the results of n executions of f. If n is non-positive this function must return the empty list.

Examples

  • repeatf( () => { return "cow"; } , 3 ) => [ "cow", "cow", "cow" ]
  • repeatf( function() { return 3; }, 2 ) => [ 3, 3 ]
  • repeatf( Math.random, 3 ) => [ <random-number>, <random-number>, <random-number> ]
