A state-of-the-art, high-performance JavaScript utility library with a small bundle size and strong type annotations.

//#region src/function/flow.ts
/**
* Creates a new function that executes the given functions in sequence. The return value of the previous function is passed as an argument to the next function.
*
* The `this` context of the returned function is also passed to the functions provided as parameters.
*
* @param funcs The functions to invoke.
* @returns Returns the new composite function.
*
* @example
* const add = (x: number, y: number) => x + y;
* const square = (n: number) => n * n;
*
* const combined = flow(add, square);
* console.log(combined(1, 2)); // 9
