Summary
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!
