i don't understand why the order of the function call inside the
_.compose(greet, format);DOESNT matter...
var realNameMap = {
'pebbles': 'penelope'
};
var format = function(name) {
name = realNameMap[name.toLowerCase()] || name;
return name.charAt(0).toUpperCase() + name.slice(1).toLowerCase();
};
var greet = function(formatted) {
return 'Hiya ' + formatted + '!';
};
var welcome = _.compose(format, greet);
@yuens1002 you could open the function definition and find out i'm sure ;)
in the underscore sourcecode look for .compose and see how they handle it
the truth is the docs really make it sound like it does matter...
// Returns a function that is the composition of a list of functions, each
// consuming the return value of the function that follows.
_.compose = function() {
var args = arguments;
var start = args.length - 1;
return function() {
var i = start;
var result = args[start].apply(this, arguments);
while (i--) result = args[i].call(this, result);
return result;
};
};
// consuming the return value of the function that follows.
_.compose = function() {
var args = arguments;
var start = args.length - 1;
return function() {
var i = start;
var result = args[start].apply(this, arguments);
while (i--) result = args[i].call(this, result);
return result;
};
};
hmm how do you guys paste code so nicely
sweet
thanks
also

backslash, of course 😝
Is there a cheat sheet for this? I'd like to bookmark it :)
and for more cool stuff
Oh. The required reading link for 5 is 404 atm.
@joeelsey you're not supposed, i just thought it's a good time to introduce it. if you copy/paste that link it should work
or google its title
Ah. Well then I just got some practice installing node again. Good times. Thanks.
I'm happy I was able to install it without too much fumbling around.
I was gonna do both 4.2 and 5.1 this weekend. Any of you high ranking officials know which one would be better to get a merge request going for first or does it not really matter?
Is there a best practice for traversing an array of object literals? .length?
@joeelsey not sure exactly what you mean, but you can open the underscore source code and see how they traverse
jquery also has code for that
@mgenev Last time I had an open pull request it seemed like it was automatically adding anything I pushed to my fork to the pull request. That seems like it could cause problems in some cases.
yea github is a bit weird like that it lumps everything to the open request
you should have no problems as long as you stick to your own folder
Yeah, I was just thinking for bigger projects. I guess you probably just have to be careful what you send to your remote while you have a request open.
branches is the best solution
Oh okay, so different branches won't go into the same pull request automatically. One day I will know all of the idiosyncrasies of github. Thank you
well, maybe not all of them
Do we need to add the code at the beginning of that link for our underscore functions to work?
in a script: '''var _ = require('lodash');'''
or loading the library from html: '''<script src="lodash_test.js"></script>'''
or loading the library from html: '''<script src="lodash_test.js"></script>'''
guess those should be backticks
in a script:
or loading the library from html:
in a script:
var _ = require('lodash');or loading the library from html:
<script src="lodash_test.js"></script>
@joeelsey remember, the browser doesn't have dependency management to require external files like Node
so you either need to use a 3rd party one like require js
or to put everything in your html file
truly doing this stuff in node is easier
so in git, if i add some new code, create a pull request, then add some new code, do i have to recreate the pull request or am i good?
haha, i think i see now the question's answered above, sort of preemptively? :)
