Example 1: In this example, we are accessing the value of an object using the path in the _.get() method

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Given object
let object = { 'c': [{ 'python': { 'java': 3 } }] };

// Use of _.get method
console.log(_.get(object, 'c[0].python.java'));

Output:

3

Example 2:  In this example, we are accessing the value of an object using the path in the _.get() method but the keys are in a sequential manner

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Given object
let object = { 'c': [{ 'python': { 'java': 3 } }] };

// Use of _.get method
console.log(_.get(object, ['c', '0', 'python', 'java']));

Output:

3

Example 3:  In this example, we are accessing the value of an object using the path in the _.get() method having a defalt value as “default”

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Given object
let object = { 'c': [{ 'python': { 'java': 3 } }] };

// Use of _.get method
console.log(_.get(object, 'c.python.java', 'default'));

Output:

'default'
