Here is the code for a JS Decision Maker that randomly selects from the list of following options: Left,Right
// Left or Right // a list containing the options var list = ['Left', 'Right']; // define the range of numbers to pick from var lowest = 0; // lowest possible index of the list var highest = list.length-1; // highest possible index of the list var number_of_decisions = 1; // how many decisions to make var this_decision = []; // array to store the results of this decision for (var j = 1; j <= number_of_decisions; j++) { // loop for the number of decisions // for each decision, generate a number between lowest and highest indices of the list var decision_number = Math.floor(Math.random() * (highest-lowest+1) + lowest); this_decision.push(list[decision_number]); //store this decision in the array } // print all the generated decisions for (j = 0; j < this_decision.length; j++) { // loop through the decision array //print each decision value followed by a comma document.write(this_decision[j]); document.write(", "); } /* Sample output */
