Lodash _.orderBy() Method

Lodash _.orderBy() method is similar to the _.sortBy() method except that it allows the sort orders of the iterates to sort by. If orders are unspecified, then all values are sorted in ascending order otherwise order of corresponding values specifies an order of "desc" for descending or "asc" for ascending sort.

Syntax

_.orderBy(Collection, [ iteratees ], [ orders ]);

Parameters:

• Collection: This parameter holds the name of the collection that needs to be sorted
• iteratees: This parameter holds the value that needs to be sorted.
• order: This parameter holds the sort orders of iterates it can be "asc" for ascending or can be "desc" for descending.

Return Value:

This method returns the new sorted array.

Example 1: In this example, we are sorting the array's patron in ascending order and age in descending order.

Output:

[
 { 'patron': 'john', 'age': 40 },
 { 'patron': 'john', 'age': 34 },
 { 'patron': 'jonny', 'age': 48 },
 { 'patron': 'jonny', 'age': 36 }
]

Example 2: In this example we uses _.orderBy() from lodash to sort the users array first by the employee field in ascending order, then by salary in descending order.

Output:

[
 { 'employee': 'hunny', 'salary': 60000 },
 { 'employee': 'hunny', 'salary': 55000 },
 { 'employee': 'munny', 'salary': 40000 },
 { 'employee': 'munny', 'salary': 36000 }
]
