Lodash _.chunk() Method
Lodash _.chunk() function is used to break the array into small chunks. Each chunk is an array of sizes as given.
Syntax:
_.chunk(array, size);
Parameters:
- array: An array to be processed by chunk function.
- size: This describes the size of the chunk.
Return Value:
It returns the array of chunks that is also an array.
Example 1: In this example, we are breaking the array by passing size ‘1’ into the _.chunk() method.
Javascript
// Requiring the lodash module // in the script const _ = require( "lodash" ); let arr = [1, 2, 3, 4, 5, 6]; // Making chunks of size 1 console.log(_.chunk(arr, 1)) |
Output:
Example 2: In this example, we are breaking the array by passing size ‘3’ into the _.chunk() method. The size of chunk can be varied and array of different data type can be used with chunk function.
Javascript
// Requiring the lodash module // in the script let _ = require( "lodash" ); let arr = [1, 2, 3, 4, 5, 6, "a" , "b" , "c" , "d" ]; console.log( "Before: " , arr) // Making chunks of size 3 console.log( "After: " , _.chunk(arr, 3)) |
Output:
Example 3: In this example, we are breaking the 2d array by passing size ‘2’ into the _.chunk() method. Using array of array with chunk.
Javascript
// Requiring the lodash module // in the script. let lodash = require( "lodash" ); let arr = [ [1, 2, 3], [4, 5, 6, 7, 8], [9, 10, 1, 2] ]; console.log( "Before: " , arr) console.log( "After: " , lodash.chunk(arr, 2)) |
Output:
Example 4: In this example, we are breaking the array of object by passing size ‘1’ into the _.chunk() method.
Javascript
let lodash = require( "lodash" ); let arr = [ { "a" : 1, "b" : 2, "c" : 3 }, { "d" : 1, "e" : 2, "f" : 3 }, { "d" : 1, "e" : 2, "f" : 3 } ]; // Array before breaking in to chunks console.log( "Before: " , arr) // Printing the first element // of the chunk as size 1 console.log( "After: " , lodash.chunk(arr, 1)[0]); |
