In this chapter, we learned about new features added in ES8, ES7, and ES6 for working with numbers, strings, arrays, and objects. We saw how arrays impact performance in math-rich applications and how array buffers can be used instead. We also walked through the new collection objects provided by ES8.
In the next chapter, we will take a look at the Symbols and Iteration protocol, and we will also explore the yield keyword and generators. A lot of exciting and cutting-edge stuff is coming your way! Hold tight!
