Package description
The pathval npm package is a utility for working with object paths. It allows you to get and set values on an object using a string path, which is useful for accessing deeply nested properties.
Get value from object
This feature allows you to retrieve a value from a nested object using a string path.
{"const pathval = require('pathval');
const obj = { a: { b: { c: 'd' } } };
const value = pathval.get(obj, 'a.b.c');
console.log(value); // Output: 'd'"}Set value on object
This feature allows you to set a value on a nested object using a string path, creating any necessary sub-objects along the path.
{"const pathval = require('pathval');
const obj = {};
pathval.set(obj, 'a.b.c', 'd');
console.log(obj); // Output: { a: { b: { c: 'd' } } }"}lodash.get is a method from the Lodash library that retrieves the value at a given path of an object. It is similar to pathval's get functionality but is part of a larger utility library.
dot-prop is a package that allows you to get, set, or delete properties from a nested object using a dot path. It is similar to pathval but also includes delete functionality.
object-path is a package that provides a full set of methods to manage paths on objects, including get, set, push, ensure, and more. It offers a broader feature set compared to pathval.

pathval.getPathInfo(obj, 'earth.country'); // { parent: { country: 'Brazil' }, name: 'country', value: 'Brazil', exists: true }
var pathval = require('pathval');
var obj = { earth: { country: 'Brazil' } };
pathval.getPathValue(obj, 'earth.country'); // 'Brazil'
