Lodash is a JavaScript library that provides utility functions for common programming tasks. One of its many features is the ability to easily get a value from an array of objects. Here's an example of how to do this:
// example array of objects
const arrayOfObjects = [
{name: 'John', age: 30},
{name: 'Jane', age: 20},
{name: 'Jack', age: 25}
];
// use Lodash to get the value of the 'age' property from the second object
const age = _.get(arrayOfObjects, '[1].age');
console.log(age);
// Output: 20
The code above uses the Lodash _.get()
function to get the value of the age
property from the second object in the arrayOfObjects
. The first argument is the array of objects, and the second argument is a string that specifies the path to the value we want to get. In this case, [1].age
means the age
property of the second object in the array.
Code explanation
-
const arrayOfObjects = [ {name: 'John', age: 30}, {name: 'Jane', age: 20}, {name: 'Jack', age: 25} ];
- This declares a constant calledarrayOfObjects
and assigns it an array of objects. -
const age = _.get(arrayOfObjects, '[1].age');
- This uses the Lodash_.get()
function to get the value of theage
property from the second object in thearrayOfObjects
array. The first argument is the array of objects, and the second argument is a string that specifies the path to the value we want to get. -
console.log(age);
- This prints the value of theage
variable to the console.
