### SharedArrayBuffer is growable

The {{jsxref("SharedArrayBuffer")}} is now growable using the {{jsxref("SharedArrayBuffer.prototype.grow()")}} method.
The maximum allowed size of the buffer is specified using the `options.maxByteLength` parameter to the [`SharedArrayBuffer()` constructor](/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer/SharedArrayBuffer#maxbytelength).
The {{jsxref("SharedArrayBuffer.prototype.growable")}} and {{jsxref("SharedArrayBuffer.prototype.maxByteLength")}} properties indicate whether the buffer can be grow, and its maximum allowed size, respectively.
([Firefox bug 1842773](https://bugzil.la/1842773)).

### ArrayBuffer is resizable

The {{jsxref("ArrayBuffer")}} can now be resized using the {{jsxref("ArrayBuffer.prototype.resize()")}} method.
The maximum allowed size of the buffer is specified using the `options.maxByteLength` parameter to the [`ArrayBuffer()` constructor](/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer/ArrayBuffer#maxbytelength).
The {{jsxref("ArrayBuffer.prototype.resizable")}} and {{jsxref("ArrayBuffer.prototype.maxByteLength")}} properties indicate whether the buffer can be resized, and its maximum allowed size, respectively.

### Float16Array Typed Arrays

{{jsxref("Float16Array")}} typed arrays are now supported, along with {{jsxref("DataView.prototype.getFloat16()")}} and {{jsxref("DataView.prototype.setFloat16()")}} for reading and setting `Float16Array` values from a {{jsxref("DataView")}}, and the {{jsxref("Math.f16round()")}} static method, which can be used to round numbers to 16 bits.

### JavaScript

- Resizeable {{jsxref("ArrayBuffer")}} and growable {{jsxref("SharedArrayBuffer")}} are now supported, allowing the size of buffers to be changed without having to allocate a new buffer and copy data into it ([Firefox bug 1884150](https://bugzil.la/1884150)).
The relevant methods and properties are:

- Grow {{jsxref("SharedArrayBuffer")}} using the {{jsxref("SharedArrayBuffer.prototype.grow()")}} method.
The maximum allowed size of the buffer is specified using the `options.maxByteLength` parameter to the [`SharedArrayBuffer()` constructor](/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer/SharedArrayBuffer#maxbytelength).
The {{jsxref("SharedArrayBuffer.prototype.growable")}} and {{jsxref("SharedArrayBuffer.prototype.maxByteLength")}} properties indicate whether the buffer can grow, and its maximum allowed size, respectively.
- Resize {{jsxref("ArrayBuffer")}} using the {{jsxref("ArrayBuffer.prototype.resize()")}} method.
The maximum allowed size of the buffer is specified using the `options.maxByteLength` parameter to the [`ArrayBuffer()` constructor](/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer/ArrayBuffer#maxbytelength).
The {{jsxref("ArrayBuffer.prototype.resizable")}} and {{jsxref("ArrayBuffer.prototype.maxByteLength")}} properties indicate whether the buffer can be resized, and its maximum allowed size, respectively.
