In this course, you’ll learn to write modern JavaScript from the ground up. But instead of going over every possible edge case, you’ll focus on the syntax that has a significant impact in your day-to-day work. As you review each construct, you’ll learn not just how to use it, but, more importantly, when to.

Your time is valuable, and this course, based on the Pragmatic Programmers’ book, Simplifying JavaScript, covers all the most important language features. And with 51 tips in total, you'll be able to jump into and out of this course easily. Before you know it, you'll be a productive and modern JavaScript developer.

Simplifying JavaScript: A Handy Guide for Software Engineers

## Short circuiting
You’ve been simplifying conditional expressions a lot in the last few tips. But there’s one more level of simplification you can use: *short circuiting*.

As the name implies, the goal of **short circuiting** is to *bypass information
checks by placing the most relevant information first*.

## Example 1: Cleaning ternary code using short circuiting

Consider the following ternary, which would fit in well with the discussion
from the previous chapter.
