You have a problem in your logic which is causing you to check the first object in the contacts array before returning a value of some kind. Remember, once a return statement is executed, the function immediately exits and does not finish iterating through any loop.

HINT: Think about where you should really be returning “No such contact”.

Also, your for loop is not quite right yet:

for (i = 0; i <= arrayLength; i++) {

First of all, you need to always declare your variables used in your code. You have not declared i. Also, since arrays are zero-indexed, think what your for loop condition should really look like.
