splice method not showing correct results

Hi i am a newbie to Javascript. i am reading a book where i am learning splice() method. Here is my code

 var fruits = ["oranges", "apples", "pears", "grapes"];
        var somefruits = fruits.splice(2, 1, "watermelons");

        for (var i = 0; i < somefruits.length; i++) {
            document.write(somefruits[i] + '<br>');
        };

Somehow the result is only showing pears. Can someonetell me why the whole array with watermelons is not replaced. Thanks,.

splice will replace the original array and return the values that been replaced. So in your case:

somefruits = fruits.splice(2, 1, "watermelons")

somefruits will be the value been replaced which is ["pear"] and the original fruits value been updated to : ["oranges", "apples", "watermelon", "grapes"]
