Lodash _.sortBy() Method

The _.sortBy() method in Lodash arranges items from smallest to largest or from A to Z, depending on what they are. It also keeps things in the same order if they're the same, like if you have two of the same numbers or words.

Syntax:

_.sortBy(collection, [iteratees]);

Parameters:

• collection: This parameter holds the collection to iterate over.
• iteratees: This parameter holds the value to sort by and is invoked with one argument(value).

Return Value: This method is used to return the new sorted array.

Example 1: In this example, we are sorting the object array using the _.sortBy() method. we have only used 'obj' for sorting the array in ascending order.

Output:

[
 { 'obj': 'moto', 'price': 19999 },
 { 'obj': 'moto', 'price': 17999 },
 { 'obj': 'oppo', 'price': 18999 },
 { 'obj': 'oppo', 'price': 15999 }
]

Example 2: In this example, we are sorting the object array using the _.sortBy() method. we have used 'obj' and 'price' for sorting the array in ascending order. so if value of 'obj' are same then it will check for the 'price' in ascending order.

Output:

[
 { 'obj': 'moto', 'price': 17999 },
 { 'obj': 'moto', 'price': 19999 },
 { 'obj': 'oppo', 'price': 15999 },
 { 'obj': 'oppo', 'price': 18999 } 
]
