When you request a file from raw.githubusercontent.com, gist.githubusercontent.com, bitbucket.org or gitlab.com, they are usually served (in the case of JavaScript, HTML, CSS, and some other file types) with a Content-Type of text/plain. As a result, most modern browsers won't actually interpret it as JavaScript, HTML, or CSS.

Let's make the example even easier. function convertDate<T extends string | undefined>(isoDate?: string): T { return undefined } 'undefined' is assignable to the constraint of type 'T' Means: What you return in the function (undefined), matches the constraints of your generic type parameter T (extends string | undefined). , but 'T' could be instantiated with a different subtype of constraint 'string | undefined'. Means: TypeScript does not consider that as safe. What if you defined your function like this at compile time: // expects string return type according to generics // but you return undefined in function body const res = convertDate<string>("2019-08-16T16:48:33Z") Then according to your signature, you expect the return type to be string. But at runtime that is not the case! This discrepancy that T can be instantiated with a different subtype (here string) than you return in the function (undefined) is expressed with the TypeScript error.

Both of the below are valid as far as T extends (...args: any[]) => any goes logFn((a, b) => a + b) logFn((a, b, c) => c) But if you refer back to the example I gave, the inner definition as: return (a, b) => fn(a, b); So option 2. will throw an error here, which is why typescript is warning you about it.

In the body of the function you have no control over the instantiation by the calling context, so we have to treat things of type T as opaque boxes and say you can't assign to it. A common mistake or misunderstanding was to constraint a type parameter and then assign to its constraint, for example: function f<T extends boolean>(x: T) { x = true; } f<false>(false); This is still incorrect because the constraint only restricts the upper bound, it does not tell you how precise T may really be.

P can't be assigned {}, since the Generic Type P can be a more defined (or restricted) type.

you can have a Type that is more specific than a boolean like this

The value 10 is assignable to the constraint of T, but it is not assignable to this particular instantiation of T. If there was no error I would passing 10 where 3 is expected!

These typeof type guards are recognized in two different forms: typeof v === "typename" and typeof v !== "typename", where "typename" must be "number", "string", "boolean", or "symbol". While TypeScript won’t stop you from comparing to other strings, the language won’t recognize those expressions as type guards.

Neurons within a type also tended to have the same dendritic arborization pattern and electrophysiological properties, but as for L23 interneurons, these properties were often not cell type–specific (figs. S3, C and F, and S4).

The remaining five types have not been previously described in L5, and we named them as follows: neurogliaform cells (L5NGCs), basket cells (L5BCs), shrub cells (SCs), horizontally elongated cells (HECs), and deep-projecting cells (DCs)

owever, many of them (~60%) had atypical axonal projection patterns compared to those previously described for SBCs, and their axon arborized mostly within L1, with only one or two side branches extending to deep layers (not deeper than L4). Despite their variable axonal projection patterns, non-neurogliaform L1 neurons shared similar dendritic and electrophysiological features (tables S1 and S2) and similar connectivity profiles (table S3) that correspond to SBCs in rat somatosensory cortex (5, 12). We thus refer to this group as SBC-like cells

An aspect of a thingxis a way of viewing it, a particular way in whichxcan be regardedor measured. For example, a woman can be regarded as a person; hence “being a person”is an aspect of a woman. A molecule has a molecular mass (say in daltons), so “havinga molecular mass” is an aspect of a molecule. In other words, byaspectwe simply meana function.

In 1980 Joachim Lambek showed that the types and programs used in computerscience form a specific kind of category. This provided a new semantics for talking aboutprograms, allowing people to investigate how programs combine and compose to createother programs, without caring about the specifics of implementation. Eugenio Moggibrought the category theoretic notion of monads into computer science to encapsulateideas that up to that point were considered outside the realm of such theory.

The line breaking algorithm can also be used to correct the line breaks made by the browser. The easiest way to do is to split a text up into lines and adjust the CSS word-spacing property. Unfortunately, Webkit based browsers do not support sub-pixel word-spacing. Alternatively, we can absolute position each word or split the line into segmants with integer word spacing. You can see the latter approach in action on the Flatland line breaking example.

Chapter 1, The Art of Community We begin the book with a bird’s-eye view of how communities function at a social science level. We cover the underlying nuts and bolts of how people form communities, what keeps them involved, and the basis and opportunities behind these interactions. Chapter 2, Planning Your Community Next we carve out and document a blueprint and strategy for your community and its future growth. Part of this strategy includes the target objectives and goals and how the community can be structured to achieve them. PREFACE xix Chapter 3, Communicating Clearly At the heart of community is communication, and great communicators can have a tremendously positive impact. Here we lay down the communications backbone and the best practices associated with using it
