Javascript Object Extensions Updated

Simon Blackwell

1/7/2016 10:29:00 PM

Javascript Object Extensions is a browser and Node.js library that adds missing and convenience functions and properties to Number, String, Boolean, Date, Array and Set.

It adds lt, lte, eq, neq, gte, gt to Number, String, Boolean, Date. Dates can be compared with precision, e.g. *.lt(date,"Y")*.

Between and outside are added to Number and String.

For language processing apps the useful functions soundex and echoes are added to String.

The methods isLeapYear and getLastDayOfMonth are added to Date as well as properties for year, fullYear, month, etc. Joex also adds data members to represent all of the parts of a Date so that they can be treated in a declarative manner.

Intersection, intersects, disjoint, coincident, crossproduct, min, max, avg are added to to Array and Set. And, some, every, and toJSON are added to Set. toJSON results in an array like representation.

Available at https://github.com/anywhic... and via https://www.npmjs.com/pa...

Wow, I just tried to get tickets in the pre-sale, and they are $255 each
plus fees! Guess I don't want to see this that bad...

I stopped reading when I saw Thomas Lahn in the list of ?experts?.

This Adam Silver cannot be serious. For a moment, I thought I was reading Adam Sandler.

I understand. The article has a bit of a learning curve once you decide to scroll the page.

I can only presume this is an objection to this library since there were no comments. I am fully aware of the danger of polyfills and will update the README of the libary to point to the referenced article. That being said, I hold there are cases where polyfills may be the only choice, i.e. where instanceof semantics must be preserved or major portions of existing code will have to be re-written (introducing yet another set of risks). This library was designed in such a way that the programmer has the ability to select which polyfills to use and can take the risks in an informed manner.

The README has been uodated to say:

"Note, there are risks in using polyfills as documented here: http://adamsilver.io/articles/the-disadvantages-of-javascript-.... However, we have found there are cases where facades and wrappers will not work, making polyfills or subclassing the only choice, i.e. where instanceof semantics must be preserved or major portions of existing code will have to be re-written (introducing yet another set of risks). We attempted to develop the library using subclassing; however, the Chrome engine does some internal checking on instances before method invocation and we were getting errors related to generic function calls and instances not being of the correct type. We will continue to endeavor to enhance this library so that it does not compel the use of a polyfill so that all choice is in the end developer's hands. Meanwhile, the library was designed in such a way that the programmer has the ability to select which polyfills to use and can take the risks in an informed manner."

I'd say that blog post lacks way too many examples, use cases and
serious studies to be called anything close to documentation.
That's more in the line of:
X is not perfect so Y, which I personally like, must be used always.
Proof:
X fails in one example.

Too mary more are needed, makes sense? :P
