typing arrays
// Arrays are variables containing multiple pieces of data.
myArray = ["value1", 2, 3, "insert fourth value here"];
// To retrieve data, you reference them via index numbers.
// KEEP IN MIND that when referencing array values, index numbers
// start at 1, not zero.
myArray[0] = "value1";
myArray[1] = 2;
myArray[3] = "insert fourth value here";
