Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The "well-known" Symbols in JavaScript
These aren't valid JavaScript (@@iterator would throw an error). They are actually internal Symbols used in JavaScript. They are used to implement features like iteration, instanceOf, and such internally. They actually might get removed or changed

📦🔓Closures in JavaScript decoded
Note that in previous editions, the ECMAScript® Language Specification used the term "lexical environment" before it decided to rename it to "Environment Record" so you might encounter this term in other definitions and tutorials.

The Evolution of JavaScript
For a new specification to be written, you need two things, a_ technical committee_, and a standard. The standard specification for JavaScript is called ECMA-262, and the technical committee is Technical Committee-39(TC39).

Show HN: We are trying to (finally) get tail-calls into the WebAssembly standard
4. Proposed something else [ https://github.com/tc39/proposal-ptc-syntax ]
While apple is against Syntactic tail calls, they’re mainly just opposed to versions of it that would remove/unrequire the tail-call optimisation they already do: https://github.com/tc39/ecma262/issues/535
For the version of it that is backwards compatible, they wouldn’t need to do anything other than recognise it as valid syntax. Their main concern is that it "could add confusion with very little benefit."

What happened to proper tail calls in JavaScript? (2021)
The spec for STC has a critique of PTC:
- performance
- developer tools
- Error.stack
- cross-realm tail calls
- developer intent
See: https://github.com/tc39/proposal-ptc-syntax#issues-with-ptc
Apple's 2016 response as to why they won't implement STC is here: https://github.com/tc39/ecma262/issues/535
- STC is part of the spec and will take too long to change.
- Now that they've implemented support for PTC, they don't want to regress web pages that rely on it.
- They don't want to discourage vendors from implementing PTC by agreeing to STC.
- They don't want to introduce confusion.
Some of these arguments about confusion and delays seem wrong hindsight, since on every point things would have been better if they'd just agreed to the compromise of STC.
- It would have been part of the spec years ago
- STC would have had a clear way for web pages to know when tail calls could be relied on (and PTC would have been optional)
- Other vendors didn't implement PTC in any case, despite no agreement on STC
- There's even more confusion as things are now

I Just Wanted Emacs to Look Nice – Using 24-Bit Color in Terminals
IME, this is like the golden age of terminal apps in general and macOS-compatible ones in particular. There are several really good terminals for macOS:
[iTerm2 app](https://iterm2.com/)
[Kitty terminal](https://sw.kovidgoyal.net/kitty/)
[WezTerm terminal](https://wezfurlong.org/wezterm/index.html)
[Alacritty](https://github.com/alacritty/alacritty)
My daily driver is WezTerm…
- Runs on Linux, macOS, Windows 10 and FreeBSD
- [Multiplex terminal panes, tabs and windows on local and remote hosts, with native mouse and scrollback](https://wezfurlong.org/wezterm/multiplexing.html)
- [Ligatures](https://github.com/tonsky/FiraCode#fira-code-monospaced-font...), Color Emoji and font fallback, with true color and [dynamic color schemes](https://wezfurlong.org/wezterm/config/appearance.html#colors).
- [Hyperlinks](https://wezfurlong.org/wezterm/hyperlinks.html)
- [Searchable Scrollback](https://wezfurlong.org/wezterm/scrollback.html) (use mouse wheel and `Shift-PageUp` and `Shift PageDown` to navigate, Ctrl-Shift-F to activate search mode)
- xterm style selection of text with mouse; paste selection via `Shift-Insert` (bracketed paste is supported!)
- SGR style mouse reporting (works in vim and tmux)
- Render underline, double-underline, italic, bold, strikethrough (most other terminal emulators do not support as many render attributes)
- Configuration via a [configuration file](https://wezfurlong.org/wezterm/config/files.html) with hot reloading
- Multiple Windows (Hotkey: `Super-N`)
- Splits/Panes (Split horizontally/vertically: `Ctrl-Shift-Alt-%` and `Ctrl-Shift-Alt-"`, move between panes: `Ctrl-Shift-ArrowKey`)
- Tabs (Hotkey: `Super-T`, next/prev: `Super-Shift-[` and `Super-Shift-]`, go-to: `Super-[1-9]`)
- [SSH client with native tabs](https://wezfurlong.org/wezterm/ssh.html)
- [Connect to serial ports for embedded/Arduino work](https://wezfurlong.org/wezterm/serial.html)
- Connect to a local multiplexer server over unix domain sockets
- Connect to a remote multiplexer using SSH or TLS over TCP/IP
- iTerm2 compatible image protocol support, and built-in [imgcat command](https://wezfurlong.org/wezterm/imgcat.html)
- Kitty graphics support
- Sixel graphics support (experimental: starting in `20200620-160318-e00b076c`)

Icons cut off when using using Konsole?
I use Konsole without any problem. Check the font. I recommend you to use one from here: https://www.nerdfonts.com/font-downloads. I personally use FiraCode medium patched with this tool to change the @ and the & symbols (ss03 and ss05). If you like that font, here you could get the codes to match your needs https://github.com/tonsky/FiraCode
-
What font are you using and why?
Fira Code with Ligatures Enabled but also Ligatures Limited - (as per wiki), to make sure those Ligatures are not where you don't want them to be.

Seriously though this is my recommendation: https://github.com/tonsky/FiraCode
-
which Font do you use?
https://github.com/tonsky/FiraCode give it try
-
Berkeley Mono Typeface
I was the same until I started using Fira Code and don't think I'll ever go back to anything else. the ligatures are worth it
