Lodash _.sortedUniq method is used to return the lowest index of the array where an element can be inserted and maintain its sorted order. Also, this method is like _.uniq except that it’s designed and optimized for sorted arrays. In _.uniq only the first occurrence of each element is kept and the order of result values is determined by the order they occur in the array.
Syntax:
_.sortedUniq(array);
Parameters:
array: This parameter holds the array to inspect.
Return Value:
This method is used to return the new duplicate free array.
Example 1: In this example, we are getting a unique array by the use of the lodash _.sortedUniq() method.
javascript
const _ = require( "lodash" );
let y = ([1, 1, 2, 3, 3, 4]);
let index = _.sortedUniq(y, [1, 1, 2]);
console.log(index);
|
Output:
[ 1, 2, 3, 4 ]
Example 2: In this example, we are getting a unique array of characters by the use of the lodash _.sortedUniq() method.
javascript
const _ = require( "lodash" );
let y = ([ 'p' , 'q' , 'r' , 't' , 't' ,
'u' , 's' , 't' , 't' , 'v' , 'w' ]);
let index = _.sortedUniq(y);
console.log(index);
|
Output:
['p', 'q', 'r', 't', 'u', 's', 't', 'v', 'w']
Example 3: In this example, we are getting a unique array of strings by the use of the lodash _.sortedUniq() method.
javascript
const _ = require( "lodash" );
let y = ([ 'chemistry' , 'computer' , 'computer' ,
'english' , 'geography' , 'hindi' , 'hindi' ,
'maths' , 'physics' ]);
let index = _.sortedUniq(y);
console.log(index);
|
Output:
['chemistry', 'computer', 'english',
'geography', 'hindi', 'maths', 'physics']
Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
