Lodash _.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:
- 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: In this example, we are getting the index number of the given value at which we can insert that value into the given array.
Javascript
const _ = require( "lodash" );
let x = [1, 2, 3, 4, 4, 4, 5, 6, 6]
let index = _.sortedIndex(x, 4);
console.log(index);
|
Output:
3
Example 2: In this example, we are getting the index number of the given value at which we can insert that value into the given array.
Javascript
const _ = require( "lodash" );
let x = [ 'a' , 'b' , 'c' , 'd' , 'e' , 'e' , 'e' , 'f' ]
let index = _.sortedIndex(x, 'e' );
console.log(index);
|
Output:
4
Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
