Hi and welcome to the forum.

You need to check if none of the names match before you return ‘No such contact’.

I hope this hint helps!

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

  • = is used for assigning values to a variable in JavaScript.
  • == is used for comparison between two variables irrespective of the datatype of variable.
  • === is used for comparision between two variables but this will check strict type, which means it will check datatype and compare two values.
