simple-getter

1. About

The simple-getter utility (for JavaScript) is just a tool to access objects and arrays nested contents through arrays of values used as selectors.

1. Installation

Import the file at:

src/simple-getter.js

It should work for both, NodeJS and browser environments.

2. Usage

You can use this utility like:

SimpleGetter(data, selector)

So for example, once it's loaded, this code should return true:

SimpleGetter(
    [0, {a: {b: [0, "foo"]}}, 2],
    [1, "a", "b", 1]
) === "foo";

You can test it even in the console of your favourite browser, if you want.

3. Why?

This utility exists in other libraries, like lodash or underscore, but with this snippet, you can be sure that you don't depend on anything else for this functionality, which I find very important, as it can help you to solve problems that, otherwise, should require more effort.

Its purpose was to be a completely minimalistic approach too.

It doesn't handle errors, but it's up to you to add 3 more lines and handle them in your preferred way.

3. License

It is ok.
