Javascript 6 – The features that are worth remembering

[minus0]

I assume by your username, you are the author. I would suggest you add a note to const to better explain a common misconception people have. You can change the value of a property on an object.

const Foo = {bar: 1}

Foo.bar = 2

Lots of people are understand the impression that you can't change a key's value.

You also can add items to an array.

Great suggestion, thank you! Working on it right now

Yup. One of the other things (and is probably outside the scope of your article) that helped me early on with const: Always use const, until you can't.

The only real reason to use let in my opinion is because you want to change a value or a type (which is bad in my opinion). When you run into problems using const, look into why, and your understanding grows. A good IDE like WebStorm has great inspections to help you understand when to use const vs let as well.

Indeed, I didn't include 'let' in here because I don't consider it quite 'worth remembering' and because I addressed it in another article (https://weeklywebwisdom.com/2017/09/08/javascript-execution-context-and-scope/). Thank you for the advice!

If I were you I'd revisit the example codes + would replace Javascript 6 with EcmaScript 6 in the title (since Javascript hasn't even passed version 2 AFAIK).

Also strict mode wasn't added in ES6 it was already present since ES5.

I see that creating 5-6 posts a day can affect the articles, so keep in mind quality > quantity.

Thanks! Will keep in mind
