javascript re-populate an array

Question

I am using:

var myArry = [];

as a global variable. I then populate the array with some data from the database. If I then want to replace the array data with new data do I have to empty / reset the original array.

Or what is the correct method?

Here are some ways to empty an array:

myArray = [];
myArray = new Array();
myArray.length = 0;
myArray.splice(0, myArray.length);

These will all work.

myArray.length = 0; will empty the array. You can then repopulate it as needed.

If it comes from the database, it would be better to clear your array since some data may be deleted.

To do so, you can write myArray = [];
