javascript-lodashHow do I use Lodash to sort an array of objects by a specific key in JavaScript?
Using Lodash to sort an array of objects by a specific key in JavaScript is a simple task.
var _ = require('lodash');
var array = [
{ name: 'John', age: 30 },
{ name: 'Jane', age: 25 },
{ name: 'Mike', age: 35 },
];
var sortedArray = _.sortBy(array, 'age');
console.log(sortedArray);
Output example
[
{ name: 'Jane', age: 25 },
{ name: 'John', age: 30 },
{ name: 'Mike', age: 35 }
]
The code above uses the Lodash sortBy
method to sort an array of objects by the age
key. The sortBy
method takes two arguments: the array to be sorted and the key by which the array should be sorted. The array is then sorted in ascending order according to the value of the specified key.
Code explanation
