Last week Axel Rauschmayer presented “The Four Layers of JavaScript OOP.” His approach to teaching JavaScript OOP is doing so incrementally, through layers. Each of the four layers builds upon the last. The lesson runs just under an hour.
- The live audience (1,500 attendees) brought certain foreknowledge to the course, represented by this graph (based on a live poll). Most individuals had knowledge of object oriented programming, whether with JavaScript or another language, and fewest had knowledge of prototype chains. [at 01:30]
- Axel walked through an overview of the 4 layers of JavaScript OOP and summarized each. [at 2:25]
- Layer 1, Single object. [at 3:55]
- Layer 2, Prototype chain. [at 14:52]
Layers 1 and 2 together form a simple core, which you can refer back to if confusion sets in. This way you can re-ground yourself at any point in the foundations of the course.
