Why I've stopped exporting defaults from my JavaScript modules - Human Who Codes
I tweeted this after realizing that a lot of problems I had with JavaScript modules could be traced back to fights with default exports. It didn’t matter if I was using JavaScript modules (or ECMAScript modules, as many prefer to call them) or CommonJS, I was still stumbling over importing from modules with default exports. I got a variety of responses to the tweet, many of which questioned how I could come to this decision. This post is my attempt to clarify my thinking.

Why Bandwidth Still Matters - DEV Community 👩💻👨💻
I remember going to a local mall in New Jersey and walking into a T-Mobile store back in 2014. I had just moved to the US the previous year, and I was just about sick of using Google Voice to keep in touch with people. Opening my laptop just to send a text or make a call wasn't very convenient. Unfortunately, it was all I could afford to do because I didn't even have a working phone at that time. I was a recent graduate and very unemployed. So I said to myself that the minute I get hired for a job I was going to get myself a new phone.

d3/d3-scale: Encodings that map abstract data to visual representation.
Scales are a convenient abstraction for a fundamental task in visualization: mapping a dimension of abstract data to a visual representation. Although most often used for position-encoding quantitative data, such as mapping a measurement in meters to a position in pixels for dots in a scatterplot, scales can represent virtually any visual encoding, such as diverging colors, stroke widths, or symbol size. Scales can also be used with virtually any type of data, such as named categorical data or discrete data that requires sensible breaks.
For continuous quantitative data, you typically want a linear scale. (For time series data, a time scale.) If the distribution calls for it, consider transforming data using a power or log scale. A quantize scale may aid differentiation by rounding continuous data to a fixed set of discrete values; similarly, a quantile scale computes quantiles from a sample population, and a threshold scale allows you to specify arbitrary breaks in continuous data.
For discrete ordinal (ordered) or categorical (unordered) data, an ordinal scale specifies an explicit mapping from a set of data values to a corresponding set of visual attributes (such as colors). The related band and point scales are useful for position-encoding ordinal data, such as bars in a bar chart or dots in an categorical scatterplot.
