lazy - API reference

API reference › @evolu/common › Function › lazy

function lazy<T>(value: T): Lazy<T>;

Defined in: packages/common/src/Function.ts:159

Creates a Lazy from a precomputed value.

Use when the value is expensive to compute and want to compute it once at definition time rather than on every call.

Example

// Computed once at definition, returned on every call
const getConfig = lazy(parseConfig(rawConfig));

// vs. computed on every call
const getConfig = () => parseConfig(rawConfig);
