The _.weave() method takes two arrays and returns an array with both arrays woven together.
Note: The array returned from _.weave() method will be woven till the shortest array, rest array values are the same.
Syntax:
_.weave(array1, array2)
Parameters:
- array1: The first array.
- array2: The second array.
Return Value: This method returns a woven array made from array1 and array2.
Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed. Underscore.js contrib library can be installed using npm install underscore-contrib –save.
Example 1: In this example, we will generate a woven array with array1’s and array2’s sizes as same.
Javascript
// Defining underscore contrib variable var _ = require( 'underscore-contrib' ); // Array1 var array1 = [1, 2, 3, 4]; // Array2 var array2 = [5, 6, 7, 8] // Generating Array using weave() method var arr =_.weave(array1, array2); console.log( "Array1 : " , array1); console.log( "Array2 : " , array2); console.log( "Woven Array : " , arr); |
Output:
Array1 : [ 1, 2, 3, 4 ] Array2 : [ 5, 6, 7, 8 ] woven Array : [ 1, 5, 2, 6, 3, 7, 4, 8 ]
Example 2: When size of array1 < size of array2
Javascript
// Defining underscore contrib variable var _ = require( 'underscore-contrib' ); // Array1 var array1 = [1, 2]; // Array2 var array2 = [5, 6, 7, 8] // Generating Array using weave() method var arr =_.weave(array1, array2); console.log( "Array1 : " , array1); console.log( "Array2 : " , array2); console.log( "Woven Array : " , arr); |
Output:
Array1 : [ 1, 2 ] Array2 : [ 5, 6, 7, 8 ] Woven Array : [ 1, 5, 2, 6, 7, 8 ]
Example 3: When the size of array1 > size of array2
Javascript
// Defining underscore contrib variable var _ = require( 'underscore-contrib' ); // Array1 var array1 = [1, 2, 3, 4]; // Array2 var array2 = [5, 6] // Generating Array using weave() method var arr =_.weave(array1, array2); console.log( "Array1 : " , array1); console.log( "Array2 : " , array2); console.log( "Woven Array : " , arr); |
Output:
Array1 : [ 1, 2, 3, 4 ] Array2 : [ 5, 6 ] Woven Array : [ 1, 5, 2, 6, 3, 4 ]
