shift-interpreter/dist/src/waterfall.d.ts

Shift-interpreter is an experimental JavaScript meta-interpreter useful for reverse engineering and analysis. One notable difference from other projects is that shift-interpreter retains state over an entire script but can be fed expressions and statement

export declare function waterfallMap<T, J>(array: Array<J>, iterator: (el: J, i: number) => Promise<T>): Promise<Array<T>>;
