To summarize, the difference in the results is because in Code 1, the splice() method is called on the new array created by om(), while in Code 2, the splice() method is called on a separate array ( newArr) created by om(). The element "my" is removed from newArr, and the resulting array has a length of 3. This method modifies the original array and returns the removed elements as a new array. It lets you change the content of your array by removing or replacing existing elements with new ones. The splice() method modifies the array in place, just like before, but since newArr is a separate array from targetArr, the modification doesn't affect the original targetArr array. The slice () method returns a shallow copy of a portion of an array into a new array object selected from start to end ( end not included) where start and end represent the index of items in that array. The splice () method is a built-in method for JavaScript Array objects. In Code 2, om(targetArr) also creates a new array with the elements from targetArr, but this time, the splice(2, 1) method is called on the newArr array itself. If you wanted return an array with everything but Orange.
So all you are doing is creating a new array with the item that you remove. split() function to create an array with elements split by ' ' and then manually iterate through that array and add '<' for each item. You can use the push () function that adds new items to the end of an array and returns the new length. Array.splice takes an index and the amount of items you want to remove at that index. push () The push () method is an in-built JavaScript method that is used to add a number, string, object, array, or any value to the Array. The splice() method returns an array containing the removed elements, so errnewArr ends up being an array with the removed element "my". Your second function you are using splice which is used to remove items from an array. It is most efficient to add data to the beginning or middle part of an array. The splice () method allows you to add one or more elements sequentially to an existing array. The splice() method modifies the array in place by removing one element at index 2. It's better to use the built-in Array method called splice (), which does the same thing just in one line of code.
In Code 1, the om(targetArr) creates a new array using the elements from targetArr, and then the splice(2, 1) method is called on that new array. More Examples At position 2, add new items, and remove 1 item: const fruits 'Banana', 'Orange', 'Apple', 'Mango' fruits. The difference in the results between the two code snippets is due to the way the splice() method works and how it affects the original array and the newly created array. , itemX) Parameters Return Value An array containing the removed items (if any).
