The Lodash _.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 will be the same.
Syntax:
_.weave(array1, array2)
Parameters: This method takes two parameters as mentioned above and described below:
- 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 lodash contrib library to be installed.
Module Installation: Lodash contrib library can be installed using the following command:
npm install lodash-contrib –save
Example 1: In this example, we will generate a woven array with array1’s and array2’s sizes as same.
var _ = require( 'lodash-contrib' );
var array1 = [1, 2, 8, 9];
var array2 = [5, 6, 7, 8]
var arr =_.weave(array1, array2);
console.log( "Array1 : " , array1);
console.log( "Array2 : " , array2);
console.log( "Woven Array : " , arr);
|
Output:
Array1 : [ 1, 2, 8, 9 ]
Array2 : [ 5, 6, 7, 8 ]
Woven Array : [
1, 5, 2, 6,
8, 7, 9, 8
]
Example 2: When the size of array1 < size of array2
var _ = require( 'lodash-contrib' );
var array1 = [1, 2];
var array2 = [5, 6, 7, 8]
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
var _ = require( 'lodash-contrib' );
var array1 = [1, 2, 3, 4];
var array2 = [5, 6]
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 ]
