Try splitting the task into smaller chunks, until you will know how to do one of them. Then focus on another one.

To make it easier, add logging to console below the function, you will get feedback right away.

console.log(displayBooks(library))
1 Like

function displayBooks(array) {
array.forEach((elem) => {
let sentence = ${elem.title}, ${elem.author}, ${elem.pages}
console.log(sentence)})
}
console.log(displayBooks(library))

I tried and I am getting the required details in the output but the step is not passing

Welcome to the forum @abhatia08

Try removing the console from inside the function.
What is the output?

Happy coding

The output is undefined after removing console.log from inside the function

How do you get a function to give a defined value?

7

By using the return keyword

What do you need the function to return?
