Hi Coders!I am trying to find a solution but the output seems to be wrong here, please let me know what I am doing wrong. Thanks in advance!

Remember, a return statement immediately stops the execution of a function and returns a value, even if that return statement is inside of a loop.

Let me ask you this. When will you know that name does not correspond to any of the contacts?

Hi bbsmooth, thanks for taking time, since in the given conditions it was given to check only with the first name, I gave the condition as if(contacts.firstname === name), else it would display “No such contact”.
even if the return statement immediately returns an answer, then I should be able to see the required ‘name’ results. the result is showing only when data doesn’t match(no such property and ‘no contact’ are showing fine). Could you assist?

Again, I ask “When do you know that name does not correspond to any of the contacts?”

If I give you a list of names on a piece of paper, how do you know if a specific name is for sure NOT on the list? After looking at the first name on the list?
