Summary: After reviewing the feasibility of adding new Runtime functionality, we realized the current state of `Runtime` makes it hard/inconvenient to add new basic functionality. It requires creating a new interface (e.g. `IRuntime2`) to declare the new APIs. Then, everywhere it is needed, both the original `Runtime` and `IRuntime2` needs to passed in to access both APIs. After discussion, we decided to introduce `IRuntime`, which will declare most of the `Runtime` functionalities. All "protected" APIs, which made sense before interfaces were introduced, will now be public. The protected static methods of `Runtime` will remain as is for the Friends to access. After we decided to cut "stable" (after incoming JSI improvements), new functionalities will be added in `IRuntime2` interface. `IRuntime2` will inherit `IRuntime` to make existing functionality easy to access. Differential Revision: D89093651
Summary: Currently, the size of a jsi `Array` is immutable. Once the `Array` is created, users can only set the element at an existing index, but not append to it. This change adds an `Array::push` API to improve ergonomics. Differential Revision: D82254334
Summary: Adds `ArrayBuffer::getMutableBuffer` to JSI. This allows the user to retrieve a `MutableBuffer` from the `ArrayBuffer`. The data referenced by the `MutableBuffer` will be alive during the entirety of the `MutableBuffer` lifespan. Addresses: facebook/hermes#1578 Differential Revision: D91264901
Differential Revision: D92993088
Summary: Add TypedArray and Uint8Array types to JSI with supporting APIs. New types: - `TypedArray`: Base class for all typed arrays - `Uint8Array`: Uint8Array type extending TypedArray New IRuntime APIs: - `buffer(TypedArray)`: Get underlying ArrayBuffer - `byteOffset(TypedArray)`: Get byte offset property - `byteLength(TypedArray)`: Get byte length property - `length(TypedArray)`: Get length property - `createUint8Array(size_t)`: Create Uint8Array with length - `createUint8Array(ArrayBuffer, offset, length)`: Create from ArrayBuffer - `isUint8Array(Object)`: Check if object is Uint8Array Differential Revision: D95245175
Summary: Add Error creation APIs to JSI to allow native code to create JavaScript Error objects of all standard types. Users can also call the static methods in `JSError` that creates a `JSError` instance that holds the intended error type. Differential Revision: D95854323
Summary: Add a JSI API to get the length of a JavaScript string in UTF-16 code units. This is equivalent to the "length" property of a JS string. New API: - `IRuntime::length(const String&)`: Returns the number of UTF-16 code units in the string. Default implementation: The default implementation in `jsi::Runtime` calls `utf16()` then returns the size. Note that the default `utf16()` implementation first converts the JS string to UTF-8, then converts that to UTF-16. This intermediate UTF-8 step does not handle lone surrogates correctly, causing code units to be "lost" in the conversion. Runtimes should provide optimized implementations when possible. The following optimized implementations are provided: JSC implementation: Uses the `JSStringGetLength` API for efficient retrieval. V8 implementation: Uses the `v8::String::Length()` API for efficient retrieval. Differential Revision: D96030262
