Summary:
We're replacing console.disableYellowBox (untyped, global hack, only warnings) with LogBox.ignoreAllLogs() (typed, local method, handles errors and warnings). rickhanlonii made the initial deprecation of this >2 years ago in https://github.com/facebook/react-native/commit/87f1e22434210ad22f526422bbda0413f59786ce . This diff finally removes the support of `console.disableYellowBox`. Users of LogBox should be using `LogBox.ignoreAllLogs`. This removal also allows us to move LogBox to strict mode flow.
Changelog: [BREAKING] [Removed] Removed console.disableYellowBox in favor of LogBox.ignoreAllLogs.

ES Modules implicitly enable strict mode. Adding the "use strict" directive is, therefore, not required.
This diff removes all "use strict" directives from ES modules.

Summary:
Right now the code frame and stack trace for metro errors are useless. This diff improved these errors by showing the metro code frame for the source of the issue, and stripping the stack trace.
Ideally we could show the metro stack trace as well, but since stack traces are tightly coupled to symbolication (and metro source code does not need symbolicated, nor could it be), this is an acceptable incremental improvement.
Arguably, even showing the code frame is inappropriate and we should show a generic crash screen with reload and report buttons.

Summary:
This diff makes a few improvements to the call stack / symbolication process:
- Removes button from unsymbolicated stack frames
- Adds a warning message for missing features without symbolication
- Reduces symbolication requests (we were re-requesting stacks when they were pending)
- Speeds up opening unsymbolicated logs (because we were re-requesting them, the components were updating a lot)

Summary:
This diff adds handling for syntax errors.
## Strategy
To do this we introduce a new log level type syntax, giving us these levels with semantics:
- `warn` - console warns, show collapsed, dismissible
- `error` - console errors, show collapsed, dismissible
- `fatal` - thrown exceptions, show expanded, not dismissible
- `syntax` - thrown exceptions for invalid syntax, show expanded, not dismissible
Syntax errors shows expanded, covers all other errors, and are only dismissible when the syntax error is fixed and updated with Fast Refresh. Once the syntax error is fixed, it reveals any previously covered fatals, errors, or warnings behind it
In many ways, this makes syntax errors the highest level error.
## Visuals
Syntax errors also have their own display formatting. Stack traces for syntax errors don't make sense, so we don't show them. Instead, we show the syntax error message and a code frame for the error.
The code frame is also updated so that is doesn't wrap and is horizontally scrollable, making it easier to read.
## Detecting syntax errors
To detect syntax errors we've updated `LogBoxData.addException` to call the parse function `parseLogBoxException`. This method will perform a regex on the error message to detect:
- file name
- location
- error message
- codeframe
If this regex fails for any reason to find all four parts, we'll fall back to a fatal. Over time we'll update this regex to be more robust and handle more cases we've missed.

Summary:
This diff improves LogBox performance by not storing and updating logs that are ignored.
Previous we stored all logs, including ignored, as a set. This was so that later, when we show a list of all logs, we would be able to show the ignored logs as well if toggled on. We stored the logs as:
```
const logs = new Set([
{
message: "Not ignored",
ignored: false,
},
{
message: "Ignored",
ignored: true,
},
// 100s more ignored logs
]);
```
But it turns out, we can have hundreds of ignored logs within seconds in some parts of the app. This means we we're re-rendering the LogBoxContainer hundreds of times with a filter on this set to filter out the ignored logs, just to change none of the content.
Now we store as:
```
const logs = new Set([
{
message: "Not ignored",
},
]);
```
Later, when we want to show ignored logs, we'll store these separately.

Summary:
# Overview
This diff adds the initial LogBox redesign implementing only Warnings for now. The following diffs include the tests for this, as well as a way to enable an experimental flag to opt-in.
Changelog: [Internal]
## Changes
To init LogBox, we've taken the core of YellowBox and rewritten it entirely.
Differences from Yellowbox include:
- Data model re-written
- More performant
- Allows a future listing of logs in order
- Allows a future toggle to show ignored logs
- Moves category into a property
- Groups by the same sequential message (as chrome does) instead of by category
- Does not store dupes of the same messages, only a count
- UI revamp
- Color and design refresh
- Does not spam UI with logs
- Only shows the most recent log
- Dismiss all button is always in one place
- Allows navigating through all of the warnings in the list, not just ones in the same category
- Collapses message to 5 lines (tap to expand)
- Collapses unrelated stack frames (tap to expand)
- Moves React stack to it's own section
- Formats React Stack like a stack frame
- Collapses any React frames over 3 deep (tap to expand)
- Adds a "Meta" information (to be expanded on later)
- De-emphasizes the source map indicator
- Better Engineering
- Rewrote almost all components to hooks (will follow up with the rest)
- Added more tests for Data files
- Added testes for UI components (previously there were none)
- Refactored some imperative render code to declarative
## Known Problems
- The first major problem is that in the collapsed state (which is meant to model the FBLogger on Comet) does not show the user how many logs are in the console (only the count of the current log).
- The way we're doing symbolication and navigation is slow. We will follow up with perf improvements
- The React Stack logic is too simple and missed cases
- We need to get properly scaled images for the close button
## What's next
Next up we'll be:
- Move over Moti's improvements to filtering and YellowBox changes since I started this
- Adding in Errors, and not using the native redbox when LogBox is available
- Adding in a list of all errors and a way to navigate to it
- Adding in Logs, so users can see console.log in the app
- Make React stack frames clickable
- And many more
