    Use ES6 Sets to Improve Javascript Performance

    javascriptJavaScript

    Using Sets in ES6 to produce lists of unique objects is faster than using arrays, and less error prone than using objects. In this lesson, we explore the pitfalls of the object approach and the speed implications of the array approach. We will then instrument the array approach and the set approach to measure the number of operations each approach performs, and it's implications on program speed.
