I am learning JavaScript and I came across a problem in learnjavascript.online
"String length Complete the function getNameLength such that it returns the length of the name that it receives."
Tests (0/2)
returns a number
returns the correct length
I did it this way but it didn't work
...ANSWER
Answered 2020-Aug-02 at 02:18Have you tried calculating the length within the function rather than in the console log? This ensures that all of the logic is first completed within the function before it is returned in the console log. Your function expects the string name, but you are passing name.length
