throttle-typescript/dist/throttled-function.d.ts

Helper that returns a throttled function (TypeScript types included - works without TypeScript also)

/**
 * Call the original function, but applying the throttle rules.
 *
 * If the throttled function can be run immediately, this calls it and returns its return
 * value, otherwise, it returns the return value of the last invocation.
 */
export declare type ThrottledFunction<T extends (...args: any) => any> = (...args: Parameters<T>) => ReturnType<T>;
