We can find the maximal value in an array by taking a variable max and repeatedly comparing it to the elements of the array using loops. Within removeMinMax(arr,prop,n) the object mm is used to control the filtering behaviour: mm. You mentioned that the values change every couple of seconds. If it is, we return the current Y value using p. apply(this, arr); // Get the index of the max value, through the built in function inArray $. apply(null, array) and Math. All these 3 are achieved, Now I need to find the minimum & maximum value in array. If we get any such element, we replace the value of “min” with a smaller value.
