memoize

Call Signature

memoize<Fn>(getter): Memoized<Fn>

Memoizes a constant or a constant function output. Subsequent calls to the function will not evaluate the given constant function, but uses a cached value instead.

Example

let i = 0
const mem = memoize(() => i++)
mem()
// => 0

mem()
// => 0

mem.clear()
mem()
// => 1

Alternatives

• Lodash - memoize

Type Parameters

• Fn extends () => any

Parameters

getter

Fn

The constant or constant function.

Returns

Memoized<Fn>

The memoized function to the constant.

Call Signature

memoize<Fn>(getter, resolver): Memoized<Fn>

Memoizes a constant or a constant function output. Subsequent calls to the function will not evaluate the given constant function, but uses a cached value instead.

Example

let i = 0
const mem = memoize(() => i++)
mem()
// => 0

mem()
// => 0

mem.clear()
mem()
// => 1

Alternatives

• Lodash - memoize

Type Parameters

• Fn extends (…args) => any

Parameters

getter

Fn

The constant or constant function.

resolver

Resolver<Fn>

The resolver that defines how the constant function should be retrieved.

Returns

Memoized<Fn>

The memoized function to the constant.
