The _.sortedIndex() method is used to return the lowest index of the array where an element can be inserted and maintain its sorted order. It uses the binary search.
Syntax:
_.sortedIndex(array, value)
Parameters: This method accept two parameters as mentioned above and described below:
- array: This parameter holds the sorted array.
- value: This parameter holds the value to evaluate.
Return Value: This method returns the index at which the value should be inserted into the array.
Example 1: Here, const _ = require(‘lodash’) is used to import the lodash library into the file.
Javascript
// Requiring the lodash library const _ = require("lodash");     // Original array let x = [1, 2, 3, 4, 4, 4, 5, 6, 6]      // Use of _.sortedIndex() // method let index = _.sortedIndex(x, 4);     // Printing the output console.log(index); |
Output:
3
Example 2:
Javascript
// Requiring the lodash library const _ = require("lodash");     // Original array let x = ['a', 'b', 'c', 'd', 'e', 'e', 'e', 'f']      // Use of _.sortedIndex() // method let index = _.sortedIndex(x, 'e');     // Printing the output console.log(index); |
Output:
4
Example 3:
Javascript
// Requiring the lodash library const _ = require("lodash");     // Original array let x = ['ajax', 'django', 'mongoDb',         'react', 'reactnative', 'yarn']      // Use of _.sortedIndex() // method let index = _.sortedIndex(x, 'ruby');     // Printing the output console.log(index); |
Output:
5
Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
