Access properties of nested objects using dot-path notation
npm install dottyAccess properties of nested objects using dot-path notation.
Dotty makes it easy to programmatically access arbitrarily nested objects and
their properties.
Here's a link to the npm page.
npm install dotty
Also see the documentation and
example.
``javascript
var dotty = require("dotty");
var object = {
a: {
b: {
x: "y",
},
c: {
x: "z",
},

};
console.log(dotty.exists(object, "a.b.x")); // true
console.log(dotty.exists(object, ["a", "b", "x"])); // true
console.log(dotty.exists(object, "a.b.z")); // false
console.log(dotty.exists(object, ["a", "b", "z"])); // false
