kandi X-RAY | ECMAScript-features Summary

ECMAScript-features is a JavaScript library typically used in Programming Style, Script Programming, Nodejs applications. ECMAScript-features has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

While creating symbols, you also can add a description to it for debugging purposes. But there was no method to access the description directly before ES2019. Considering this, ES2019 introduced a read-only description property to retrieve a string containing the description of the Symbol. This gives the possibility to access symbol description for different variations of Symbol objects.

Why String.prototype.substr() seems to be deprecated?

QUESTION

Why String.prototype.substr() seems to be deprecated?

Asked 2018-Dec-11 at 18:50

It is mentionned on the ECMAScript standard here that :

... These features are not considered part of the core ECMAScript language. Programmers should not use or assume the existence of these features and behaviours when writing new ECMAScript code. ECMAScript implementations are discouraged from implementing these features unless the implementation is part of a web browser or is required to run the same legacy ECMAScript code that web browsers encounter.

There is also a red warning on MDN : String.prototype.substr() MDN doc

Does anyone know why (ECMAScript standard say that) programmers should not use or assume the existence of String.prototype.substr ?

...

Because it's never been part of the standardized language. It wasn't in the ECMAScript 1 or 2 specs at all, and only appears in ECMAScript 3 in Section B.2 ("Additional Properties") (and subsequent editions in similar annexes), which said:

Some implementations of ECMAScript have included additional properties for some of the standard native objects. This non-normative annex suggests uniform semantics for such properties without making the properties or their semantics part of this standard.

Moreover, substr is largely redundant with substring, but the second argument has a different meaning, as well as with slice.

In pragmatic terms, I'd be surprised if you found a mainstream JavaScript engine that didn't provide it.
