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.Â
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.
// Defining lodash contrib variable var _ = require('lodash-contrib');   // Array1 var array1 = [1, 2, 8, 9];   // 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, 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
// Defining lodash contrib variable var _ = require('lodash-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 array2Â
// Defining lodash contrib variable var _ = require('lodash-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 ]
