by Sacha Greif A Look Back at the State of JavaScript in 2017In advance of the 2017 State of JS survey results, our panel of experts looks back on the past yearOne of the highlights of last year’s State of JavaScript survey results was the great panel of experts we assembled to analyze the results.

A few weeks ago we released Firefox 57, also known as Firefox Quantum. I work on SpiderMonkey performance and this year I spent a lot of time analyzing profiles and optimizing as many things as possible. I can't go through all SpiderMonkey performance improvements here: this year alone I landed almost 500 patches (most of them performance related, most of them pretty boring) and other SpiderMonkey
Understanding how people use their devices often helps in improving the user experience. However, accessing the data that provides such insights — for example, what users type on their keyboards and the websites they visit — can compromise user privacy.

These errors satisfy the standard Go error interface, but are implemented using a custom type, upspin.io/errors.Error, that has properties that have proven valuable to the project. Here we will demonstrate how the package works and how it is used. The story holds lessons for the
Every year, we survey as many venture-backed startup founders as possible to figure out what it's like to run a technology company right now. This year, we got more responses than ever before — 869 — giving us an even more precise pulse on what entrepreneurs think, feel, fear, and value.
