Processing Arrays non-destructively:
loops, the Array method
, and the Array method
. It explains how the latter two work. To get a feeling for how these constructs differ, the following functionality is implemented with each of them (if possible):
- Filtering an input Array to produce an output Array
- Mapping each input Array element to one output Array element
- Expanding each input Array element to zero or more output Array elements
- Filter-mapping (filtering and mapping in one step)
- Computing a summary for an Array
- Finding an Array element
- Checking a condition for all Array elements
relative-deps: managing local dependencies without the limitations of

How we converted our Node.js library to Deno (using Deno)
“At EdgeDB, we built and maintain a first-party client library for Node.js that’s available as the edgedb module on NPM. However, Deno uses a totally different set of practices to handle dependencies, namely direct URL imports from public package registries like deno.land/x. We set out to find a simple way to “Denoify” our codebase; that is, generate a Deno-compatible module from our existing Node.js implementation with minimal refactoring.”
They used Deno’s Node.js compatibility library and wrote a codemod to add the filename extension
.ts to imports, change usages of global Node.js variables such as
Buffer to Deno-specific imports, etc.
