⌨️ Alternatives to JavaScript's if…else statement

1️⃣ Switch Statement
Finds the matching value of an expression and executes the code block associated with the matching value.

2️⃣ Ternary Operator
Checks a condition and executes the first expression if the condition is true. Otherwise it runs the second expression.

3️⃣ Jump / Dispatch Table

Stores value-function pairs in an object to quickly fetch and run a function based on a value (which is treated as an object key).

4️⃣ Dynamic Dispatch
This pattern involves selecting which polymorphic method to call based on an object’s type.

I know I know, you probably won't ever need to swap two variables. But this is a cool demonstration for how the destructuring assignment works in JavaScript.

This syntax is used to take an array or items in the right hand side and assign them to correspondingly positioned variables in the left hand side.

👉 We use that here to assign b to a, and a to b.

⌨️ Promises from the Ground Up

Josh notes that in order to truly understand promises, a fundamental part of modern JS development, we need “a surprisingly deep understanding of how JavaScript works and what its limitations are”. Luckily, this tutorial covers all the critical context you need.
