We can use something like this:
async function resolveToNumber () {
const promise = Promise.resolve(1)
const [error, result] = await to(promise)
console.log(error, result) // [null, 1] -> Here we have the result, and error will be null
}
Using an index.js
file in each component or feature folder serves as a convenient way to organize and simplify imports within your project. Here's why it's commonly used:
Cleaner Imports: When you have an index.js
file in a folder, you can use that file to re-export the main components, functions, or objects from that folder. This allows you to import them using a cleaner syntax without needing to specify the full path to the individual files.
Abstraction of Implementation Details: The index.js
file abstracts the internal implementation details of a component or feature. Other parts of the application don't need to know the specific file names or structure within the folder; they only need to import from the folder's root.
Easier Refactoring: If you decide to reorganize your files or rename them, you only need to update the index.js
file's export statements. This prevents you from having to update import paths across your entire codebase.
