+* 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 {Array<(...args: any[]) => any>} funcs The functions to invoke.
+* @returns {(...args: any[]) => any} 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
