To redirect to another webpage using JavaScript, we can make use of the window.location object which represents the current URL or location of the browser window. There are several methods to set this location to a new URL, but the three most commonly used methods are:

Redirection using the href

To redirect to another webpage using JavaScript, you can use the window.location.href property.

Here’s an example:

window.location.href = "https://www.example.com";

This will redirect the current webpage to the URL mentioned in the href property.

Using the assign method

The assign() method sets the URL property of the Location object to a new value. This method has the effect of loading the new URL in the same frame or window as the calling page.

Example code:

window.location.assign("http://www.example.com");

This will redirect the browser to the webpage specified in the parameter, i.e., http://www.example.com.

Using the replace method

The replace() method is similar to the assign() method, but it differs in that it replaces the current history entry instead of creating a new one. This means that when you use the back button in the browser, you will jump back to the page before the one that used replace().

Example code:

window.location.replace("http://www.example.com");

This will redirect the browser to the webpage specified in the parameter, i.e., http://www.example.com, and eliminate the current page from the browsing history.

Conclusion

In conclusion, we have seen how to redirect to another webpage using two different methods in JavaScript. The assign() method navigates to a new URL and creates a new entry in the browsing history, while the replace() method navigates to a new URL and replaces the current entry in the browsing history. It’s important to note that you should only use these methods where necessary and with caution, as they may affect the user experience and browser performance.

In JavaScript, you can remove a specific item from an array by using the splice() method. The splice() method changes the content of an array by removing or replacing elements.

The syntax for splice() method is as follows:

array.splice(index, count, item1, item2, ...)

The first parameter of the splice() method specifies the index of the array where you want to start removing elements. The second parameter specifies the number of elements to remove.

Remove a specific item from an Array

For example, to remove the element at index 2 from the following array:

let array = ["apple", "banana", "orange", "pineapple"];

You can use the splice() method as follows:

let removedItem = array.splice(2, 1);

The splice() method will remove the element at index 2 (“orange”) from the array and return a new array that contains the removed element. In this case, removedItem will contain the value “orange”.

If you want to remove multiple elements from the array, you can specify the number of elements to remove as the second parameter of the splice() method. For example:

let removedItems = array.splice(1, 2);

This will remove two elements starting at index 1 (“banana” and “orange”) and return a new array that contains the removed elements.

Insert new elements at a specific index of an Array

If you don’t want to remove any elements from the array, but want to insert new elements at a specific index, you can specify the number of elements to remove as 0 and pass the new elements as additional parameters. For example:

array.splice(2, 0, "grape", "pear");

This will insert the elements “grape” and “pear” at index 2 of the array without removing any elements.

In summary, the splice() method in JavaScript can be used to remove a specific item from an array by specifying the index and count of elements to remove. It can also be used to insert new elements at a specific index of the array.
