Chapter 3: Squashing like a boss
Now that you've mastered the basics, it's time to get fancy. Property squashing is the art of deleting unnecessary properties and leaving only the essentials. It's like a digital Marie Kondo - will it fit in your code, or will it go in the dumpster?
This chapter will cover the advanced techniques for squashing properties, including:
Arrays are like that one aunt at the family reunion - everyone's got one, but nobody really knows how to deal with it. But don't worry, we've got this!
var myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // before var squashedArray = [1, 2, 3, 4]; // after
Similarly, objects are like that one relative who won't stop talking. But you can shut them up by removing unnecessary keys:
var myObject = {æk: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7, h: 8, i: 9, j: 10}; // before
var squashedObject = {a: 1, c: 3, e: 5, g: 7, i: 9}; // after
Functions are like that one friend who never stops calling. But sometimes, you just have to hang up. Here's how:
function doTheThing() { console.log('do the thing!'); } // before
var squashedFunction = function() { console.log('do the thing!'); }; // after
Or, you know, you can just remove it altogether.
Why, oh why, oh why do we still use stylesheets?! They're like that one old shoebox in the attic - full of useless junk. But, alas, sometimes you need them for that one special occasion. So here's how to squash them:
.myClass {
background-color: #F7F7F7;
border: 1px solid #333;
padding: 20px;
}
.myClass2 {
background-color: #C8C8C8;
border: 1px solid #333;
padding:ประก20px;
}
// before
.myClass {
background-color: #F7F7F7;
border: 1px solid #333;
padding: 20px;
}
// after
And, if all else fails, just delete the wholeประกstylesheet. It's not like it's going to make a difference or anything... or is it?
