Suppose we want a set of unique { x, y } points to plot on a graph.

this expression:

new Set([
  { x: 1, y: 1 },
  { x: 1, y: 1 },
]);

The following section is not part of monet.js documentation, but I think it's worth showing how we can compose readers using fp-ts.

Reader composition

Let's say we have the following piece of code:

interface Dependencies {
  logger: { log: (message: string) => void }
 env: 'development' | 'production'

/** Used by Flavor to mark a type in a readable way. */
export interface Flavoring<FlavorT> {
  _type?: FlavorT;
}
/** Create a "flavored" version of a type. TypeScript will disallow mixing flavors, but will allow unflavored values of that type to be passed in where a flavored version is expected. This is a less restrictive form of branding. */
export type Flavor<T, FlavorT> = T & Flavoring<FlavorT>;

/** Used by Brand to mark a type in a readable way. */
export interface Branding<BrandT> {
  _type: BrandT;

"For services to the PureScript Community, Gary Burgess!"

You've done it, Gary. Moore, Lineker, Coleman, and now Burgess. All the work was worth it. The halls erupted with praise. Children dressed as Space Ghost, teens with "I only get high on Halogen" t-shirts, a giant banner held aloft with the message, "Tuple @garyb me". Through the noise of the crowds and Phil's uninterpretable Northern accent, he barely managed to hear his theme tu-

Workshop sessions

First we split into groups of 5 and asked:

What experience do you have of coaching or mentoring? What’s the difference between mentoring and coaching?

Session 1

Once we’d committed to confidentiality and making the workshop a safe space, in pairs we covered:

What is it like doing your job?
