There is a simpler way to do this rather than passing null as the second argument to reduce and then checking for null to distinguish the first iteration.

If you don't include a second parameter to reduce then the first item in the array will be used for the accumulator, what you are calling here "currentHighestEarner".

Therefore it's always going to check against a person object and it's salary, so you don't need to check for null. :)

Thanks for sharing Dom. Your videos always get me thinking "Hmm, interesting, but how else could I achieve the same, or better result" - and I ended up writing this;

const [theHighestEarner = null, theSecondHighestEarner = null] = people.sort((a, b) => b.salary - a.salary);

The advantage of using a sort method, is you can then use deconstruction to return not only the top salary, but the top 2 (or more), for example.

Hello sir wahich theme did you use vs code

I want more. Even our professor told us not to pay attention to reduce() since its rarely used. Can you give more practical exams of .reduce()?

[lardosian]

Anymore plans for Rust, you did a neat series on it a few years back.

most if not all array loop method in javascript can be done with just one forEach and an external variable / let

Always Always Always high quality and underrated JS Channel! Finally something more in-depth thank you Dom!

I also feel like learning the reduce method made me a better programmer. I feel like I can get it to do anything...eventually.

I have learned something new, thank you 🙏🤓😄😌👏😍🤩😘🤗👍

The currentHighestEarner == null is just there to prevent that initial error right?

Obviously it still checks the second conditional but im a bit confused because in my mind it would return the person as null as soon as currentHighestEarner == null becomes true.

[tranphat]

I think we should let the initial value by the people[0] rather than null

thx for your work - aspecially for pronounce and gramaticly correct speech :) It is make my own soft-skills better on a common themes, linked with web development :)

[podstrahuy]

You may use 0 as initial value so you won't need to make that ugly condition.

Finally, I understand the reduce() method. Thanks to you, Dom.
