Useful functions. That's all.

Installation

npm install broom-closet

Functions

tryCatch(fn)

Calls fn and catches any exceptions, returning an array, [error, result] with the possible caught error as the first item and the result of the function as the second item. Handy for more implicit control flow and avoiding the scope issues try/catch blocks sometimes cause.

Works as both async or sync.

Example:

import tryCatch from "broom-closet/try-catch";
import { fs } from "node:fs/promises";

const [error, result] = tryCatch(mightThrow());
const [error, stat] = await tryCatch(fs.stat("/path/to/file"));

Added in v0.0.1

prepareArgs(fn, ...args)

Prepare a function for future calls by handing it some parameters. This is sort of like currying, except that there's no accounting for number of arguments.

Example:

function sum(x, y) {
  return x + y;
}

const addOne = prepareArgs(sum, 1);
addOne(8); // returns 9
