TypeScript

TypeScript is an open source programming language developed by Microsoft and first released in 2012. It is designed to add type safety to JavaScript while conforming as closely as possible to the syntax and semantics of the ECMAScript standard.
It is a syntactical superset of the JavaScript programming language; all valid JavaScript source code is also valid TypeScript source code, but not vice-versa. TypeScript compiles (or transpiles) to JavaScript, meaning that it can be utilized to target any JavaScript environment. It can be used to develop JavaScript for both client-side and server-side applications.

📚 Docs or angular.io bug report
Description
Currently, we do not have glossary entry for template
#41877 improves parsing of jsdoc comment text as well as giving the language service the option of providing display parts for comments instead of text. Currently everything is just "text"
except for links. However, with small tweaks to code like getCommentDisplayParts
in services/jsDoc.ts, it would be possible to format @param
names as "parameterName"
, @template
names as `"typeParameter

Version alpha 27 => working not as expected at breakpoint desktop

Describe the bug
When applying a dark theme to the Docs page, the table still has white and light gray background colors. This obviously ruins the readability of the table as the text color is also a light gray. There is a hardcoded background-color: white;
value applied to the table tr
element.
To Reproduce
Steps to reproduce the behavior:
- Use a dark theme for the docs page

What cheatsheet is this about? (if applicable)
Basic cheatsheet
What's your issue or idea?
content duplication
There are two identical subheading, Types or Interfaces?.
And following contents are almost the same.
I think It is better to be deduplicated.
I'd appreciate it if you could consider it for the next reader. :)

Recently, we created a new lint category called a11y
. This new category is meant to be generic and work for JSX and HTML at the same time.
At the moment, we ported only two rules and we should to the same for most of the a11y-jsx
