A Gentle Introduction to Prepack, Part 1

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

  • Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

PriorityQueue.js uses a binary heap to ensure the highest priority item is always available to dequeue, and sorts on enqueue. A dynamically resizing Array can be used to model the binary heap, for a simpler and more efficient implementation.
/**
* For compare function return:
* - Less than zero: item1 has higher priority than item2.
* - Zero: same.
* - Greater than zero: item1 has lower priority than item2.
*/
export type CompareFunction<T> = (item1: T, item2: T) => number;
export class PriorityQueue<T> {
_items: Array<T>;

How to use:

  1. Take the download.sh file and put it into a directory where you want the files to be saved.
  2. cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
  3. Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

Make JavaScript readonly propertys writable (example for overwriting navigator.userAgent; useful for unit tests -> browser detection)
