YourJS – 1st Pass

I finally have the 1st pass of YourJS available to the public!!!

What is YourJS?

YourJS is a fully customizable JavaScript library which gives the developer more control than ever before.

Who controls the codebase?

Everyone does! All you have to do is sign up and you can start writing code that can be included in YourJS.

How do I design and download my own library?

As of right now there is a section called Snippets which is a repo of code that can be included in your custom JS library. You can browse the snippets, add the ones you like to the build and then go to the build page to build the library from the selected snippets. Finally, you will have the opportunity to name your library (this will be the variable name added to the global namespace for your utility library).

What development plans are there?

  • Port most functionality available in jPaq over to YourJS.
  • Add an examples section similar to the one that exists on jPaq.org.
  • Include a buildable version of the library which includes documentation.
  • A link share for all other JS sites.

I have a lot of ideas for YourJS so the sky is the limit! Let me know if you have any suggestions and perhaps I will be able to include them in the next iteration of changes. :cool:

JavaScript Snippet – getClass()

If you have been using JavaScript for a little bit you probably already know how to determine a variable’s class constructor, but just in case you are overthinking it here is a hint: variable.constructor. :-) Of course, many times I like to make functions that will spit my results for me so here is one that will take any variable and spit out its class constructor:

OK, yeah I know that JavaScript doesn’t really have classes but prototypes but most people think of them as classes so that is why this is called getClass(). The one thing you will notice is that if null or undefined is passed into the function, the same value will be passed back since those are the only two things in JavaScript that don’t have corresponding prototypes. Have fun! :cool:

JavaScript – Getting Function Parameter Names

Two years ago I wrote a post about how to pass arguments by name in JavaScript. Recently I have started to ramp a new project call YourJS and found a need to be able to read the names of the parameters of the given function. The following getParamNames() function takes an arbitrary function and returns an array of its parameter names:

Using this function is quite simple. Let’s say that getParamNames() and the function below are defined:

function repeat(string, times, opt_delimiter) {
  opt_delimiter = arguments.length > 2 ? opt_delimiter + '' : '';
  return new Array(times + 1).join(opt_delimiter + string).replace(opt_delimiter, '');

Running getParamNames(repeat) will result in the following:

>>> getParamNames(repeat)
["string", "times", "opt_delimiter"]

Running getParamNames(getParamNames) will result in the following:

>>> getParamNames(getParamNames)

Pretty cool, right?!?! Have fun! :cool:
