With the help of bisector.center() method, we can insert the element V in an array such that V is closest to the very ith element in an array by using this method.
Syntax:
bisector.center(array, x)
Parameter: This function has the following parameter as mentioned above and described below:
- array: It is an array of values which is passed as parameter.
- x: It is the value to be inserted.
Return Value: It will return index of an array after insertion of new element.
Note: To execute the below examples you have to install the d3 library by using this command prompt we have to execute the following command.
npm install d3
Example 1: In this example we can see that by using bisector.center() method, we are able to insert the new element in such a way that the new element is very closest to ith element in an array by using this method.
Filename: index.js
// Defining d3 contrib variable  var d3 = require('d3');   var bisect = d3.bisector(i => i.int) var gfg = bisect.center([1, 2, 3, 4, 5], 4)   console.log(gfg) |
Output:
0
Example 2: Filename: index.js
// Defining d3 contrib variable  var d3 = require('d3');   var arr = [] for(var i = 0; i < 5; i++) {     arr.push(i); }   var bisect = d3.bisector(i => i.float); var gfg = bisect.center(arr, 4);   console.log(gfg); |
Output:
0
Note: The above program will compile and run by using the following command:
node index.js
