Can anyone write this code in ES5 or in easy way?

Tell us what’s happening:

Your code so far

// Add your code below this line

var averageRating = watchList.filter(x => x.Director === "Christopher Nolan").map(x => Number(x.imdbRating)).reduce((x1, x2) => x1 + x2) / watchList.filter(x => x.Director === "Christopher Nolan").length;;

// Add your code above this line

Why don’t you try to write the solution to the challenge in your own way first? You can try to write it using ES5 or earlier JavaScript syntax. The key is that you do it yourself. If you get stuck, reply back to this post with the code you have tried to write.

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 easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.
