Echo JS 0.11.0

There's a misunderstanding: I mainly use `slice` too. I only use `substr` if I have the length of the substring I need. That's its added value.

What I stopped using altogether is `substring`.

substring and slice are the same for most cases (the differences are explained in the article). The *real* alternative is substr.

The second technique doesn't actually remove the property: it creates another object without a property. It's widely used if immutability is a constraint.

If you want another proper way, you can use Reflect.deleteProperty.

Whoa! This looks so cool!

... Except the title of this post. Seriously, it sounds like spam.

How does it feel to bother other people for a living?

Oh FFS!

Not only I'm not going to star it, but I downvoted this post because of the obvious SPAM and I'll let moderators know about it.

Why should we care about something in Rust in Echo *JS*?!
