String.prototype.substr() deprecation

[Martii]

What’s missing?

https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String/substr migration.

Why?

Because JavaScript (ECMAScript) API has issues with keeping constant methods in place and wants to make it look like they are unique outside of C/CPP. 😸
