memoObject

The memoObject() function builds a proxy around a memoized object. The getter is evaluated lazily on first access, then all reads/writes target the same object.

Interactive example

Syntax

function memoObject<
	GenericOutput extends object
>(
	getter: () => GenericOutput
): GenericOutput;

Parameters

• getter : Function called on first access to produce the proxied object.

Return value

A proxied GenericOutput object:

• reads (obj.prop) return values from the memoized object;
• writes (obj.prop = value) mutate the memoized object;
• Object.keys() and the in operator reflect keys after writes.
