For each of the exercises below, assume you are starting with the following people array. and use javascript var people = ["Greg", "Mary", "Devon", "James"]; Write the command that gives the indexOf where "Mary" is located. Write the command that gives the indexOf where "Foo" is located (this should return -1 as “Foo” not exist). Redefine the people variable with the value you started with. Using the splice command, remove "Devon" from the array and add "Elizabeth" and "Artie". Your array should look like this when you are done ["Greg", "Mary", "Elizabeth", "Artie", "James"]. Create a new variable called withBob and set it equal to the people array concatenated with the string of "Bob". Display the elements in both ascendant and descendant orders.
