The handler.get() method is a trap for the [[Get]] object internal method, which is used by operations such as property accessors.

The Reflect.deleteProperty() static method is like the delete operator, but as a function. It deletes a property from an object.

The handler.construct() method is a trap for the [[Construct]] object internal method, which is used by operations such as the new operator. In order for the new operation to be valid on the resulting Proxy object, the target used to initialize the proxy must itself be a valid constructor.

The message data property of an Error instance is a human-readable description of the error.

The non-standard stack property of an Error instance offers a trace of which functions were called, in what order, from which line and file, and with what arguments. The stack string proceeds from the most recent calls to earlier ones, leading back to the original global scope call.

The fill() method of TypedArray instances changes all elements within a range of indices in a typed array to a static value. It returns the modified typed array. This method has the same algorithm as Array.prototype.fill().

The reverse() method of TypedArray instances reverses a typed array in place and returns the reference to the same typed array, the first typed array element now becoming the last, and the last typed array element becoming the first. In other words, elements order in the typed array will be turned towards the direction opposite to that previously stated. This method has the same algorithm as Array.prototype.reverse().

The buffer accessor property of TypedArray instances returns the ArrayBuffer or SharedArrayBuffer referenced by this typed array at construction time.

The Math.E static data property represents Euler's number, the base of natural logarithms, e, which is approximately 2.718.

The set() method of TypedArray instances stores multiple values in the typed array, reading input values from a specified array.
