Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

  • assertArraysEqual: console logs a message indicating if 2 given arrays are or not equal.
  • assertEqual: console logs a message indicating if 2 given primitive values are or not equal.
  • assertObjectsEqual: console logs a message indicating if 2 given objects have or not the same properties.
  • countLetters: receives a string as argument and returns an object with the all the letters from the string as key and the times that letter is repeated as value.
  • countOnly: returns how many instances of each string were found in a given string array.
  • eqArrays: returns true if 2 given arrays are equal and false if they are not.
  • eqObjects: returns true if 2 given objects have the same properties and false if they don't.
  • findKey: takes an object and a callback, scans the object and returns the key similar to the callback result.
  • findKeyByValue: takes an object and a property value as arguments and returns the correspondent key or undefined if the key is not in the object
  • flatten: transform a 1 level matrix into an array with the values that it contains.
  • head: takes an array and returns first element of that array.
  • letterPositions: takes a string returns an object with each letters as propert and their indices as a value.
  • middle: returns an array with the middle value of a given array. If the given array 0, 1 or 2 values it returns an empty array; if it has more than 3 values and its length is even it returns 2 middle value and if the length is odd it returns the middle value.
  • tail: takes an array and returns a copy without the first value.
  • takeUntil: returns a new array taking the elements from the beginning of given array stoping when the condition in a given callback function is fullfilled.
  • without: takes 2 arrays, 1 with a set of values and other with the values to be removed from the first one and returns an array with the remaining values.

The following dependencies are used to testing:

chai: ^4.3.1, mocha: ^9.2.2
