I'd like to tell the difference between valid and invalid date objects in JS, but couldn't figure out how: var d = new Date("foo"); console.log(d.toString()); // shows 'Invalid Date' console.log(typeof d); // shows 'object' console.log(d instanceof Date); // shows 'true' Any ideas for writing an isValidDate function? Ash recommended Date.parse for parsing date strings, which gives an authoritative

The typical way to loop x times in JavaScript is: for (var i = 0; i < x; i++) doStuff(i); But I don't want to use the ++ operator or have any mutable variables at all. So is there a way, in ES6, to loop x times another way? I love Ruby's mechanism: x.times do |i| do_stuff(i) end Anything similar in JavaScript/ES6? I could kind of cheat and make my own generator: function* times(x) { for (var i = 0

I'm looking for a way to show only the formulas I installed without the installed dependencies. I want to have a list of all the programs I actually installed, without all noise of the dependencies. I do know about brew list which lists all installed formulas. I also know that brew graph gives me a dependency graph in the graphviz Or in other words: I want to have the minimal set of formulas to re

I'm generally clear on bundler Gemfile options, but I'm not sure why rspec (specifically, rspec-rails) should be in both test and development. Here are my test groupings: group :development, :test do gem 'rspec-rails'gem 'faker' end group :test do gem "factory_girl_rails"gem "capybara"gem 'guard-rspec'gem 'rb-fsevent'gem 'growl' end Does this look ok?
