After some hours of trying, I got duplicated results! I don't know where the problem lies. Please help.

Question

Recursively adding names in deep nested object
https://code.sololearn.com/ca10a9A19a11/?ref=app

Answer 1

because you add 'name' property how many times there's keybwich are not array ('name' and 'value')...

to get only names, don't iterate keys, just do:

function addNames(tree){
return tree.name+tree.children.reduce((a,o) => a+addNames(o),"")
}

if you are not sure that 'children' contains an array and/or children is defined:

function addNames(tree){
return tree.name+(tree.children && Array.isArray(tree.children) ? tree.children.reduce((a,o) => a+addNames(o),"") : "")
}

visph I'm here again good friend. I got duplicated results. I don't know why. So close

Answer 3

visph aha I seee. I get it now! I was so close. Thanks bro ☺️ ☺️ ☺️ ☺️ ☺️

Answer 4

visph i think I've noticed a pattern in approaching such problems. First, finding the simplest form of the problem and then writing code to solve that but when there's a difference in the data type or structure, an if statement is used together with the function itself to cater for it. That's what I realized. I'll apply this method to the other questions ☺️☺️☺️. Thanks @visph

Answer 5

visph aha cool 😎 😎 😎

Answer 6

maybe: I must confess that my mind / brain works usually more well with the intuitive / instinctive approach ;P
