Taming Data using Array and Object methods

I remember when I was going through my college engineering math courses. On a regular basis we were introduced to new concepts such as differential equations, integrals, and Fourier transforms. While learning these was fairly straightforward, what frequently tripped us up on tests was the algebra: the fundamentals that we’d learned several years’ earlier.

I see a similar problem today. With so many language features being added to JavaScript, such as generators, async/await, and promises, and so many new libraries and frameworks, we often forget the fundamentals: the powerful functions available on Array and Object. These functions can make it easier to filter, extract, transform, and summarize data. In this talk, I’ll go over the fundamental functions and language constructs that Array and Object provide. Whether you’re fairly new to JavaScript or are a seasoned pro, it’s good to review the fundamentals.
