() Returns a new array with all sub-array elements concatenated into it recursively up to the specified depth. Result of the above example-3 is: // expected output: Array () Returns the index of the last element in the array that satisfies the provided testing function, or -1 if no appropriate element was found. Months.splice(4, 1, 'May') // replaces 1 element at index 4 Months.splice(1, 0, 'Feb') // add at index 1 We will demonstrate how to add or remove the item in it.

() The reverse () method of Array instances reverses an array in place and returns the reference to the same array, the first array element now becoming the last, and the last array element becoming the first. Now we will take several examples of splice() method: Example1 -Remove 2 elements from index 2 The third and subsequent arguments are optional they specify elements to be added to the array.The second argument specifies the number of elements to remove.If the sliced portion is sparse, the returned array is sparse as well.
