javascript add item to array in the beginning

sure! adding an item to an array in javascript is a common operation that can be done using several methods. here's a tutorial on how to add an item to the beginning of an array in javascript:

to add an item to the beginning of an array, you can use the `unshift()` method. this method modifies the original array and adds the specified item(s) to the beginning of the array. here's how you can use it:

in the code example above:
1. we first define an array called `fruits` containing three elements: 'apple', 'banana', and 'orange'.
2. we then use the `unshift()` method to add the string 'grape' to the beginning of the `fruits` array.
3. finally, we output the modified array to the console, which now contains 'grape' as the first element.

it's important to note that the `unshift()` method modifies the original array and returns the new length of the array. this method can add multiple items at once by passing them as separate arguments to the method.

i hope this tutorial helps you understand how to add an item to the beginning of an array in javascript using the `unshift()` method.
