Lodash _.splitAt() Method
The Lodash _.splitAt() method takes an array and a numeric index and returns a new array containing two embedded arrays made by splitting the original array at the provided numeric index.
Parameters: This method takes two parameters as mentioned above and described below:
- array: The array to be split.
- numeric_index: The index at which array is to be split.
Return Value: This method returns a newly created array containing two arrays.
Example 1: In this example, we will split an array using this method at the 4th index.
Array : [ 1, 3, 6, 8, 9, 11, 3 ] Numeric Value : 4 Generated Array : [ [ 1, 3, 6, 8 ], [ 9, 11, 3 ] ]
Example 2: In this example, we will split an array using this method at index 0, so will get one empty and the other same as the original array.
Array : [ 1, 3, 6, 8, 9, 11, 3 ] Numeric Value : 0 Generated Array : [ , [ 1, 3, 6, 8, 9, 11, 3 ] ]
Example 3: This method is safe for indexes outside ranges.
Array : [ 1, 3, 6, 8, 9, 11, 3 ] Numeric Value : 20 Generated Array : [ [ 1, 3, 6, 8, 9, 11, 3 ],  ]
