Recently, while working on a pre-existing website with JavaScript code, I made an interesting discovery.
I noticed that the code was accessing array items in a unique way:
var value = myArray[0, 1];
This seems to be retrieving the second item of the array. However, I am puzzled by how it differs from simply using:
var value = myArray[1];
Even when I tried changing the number before the comma, the result remained the same - always returning the second item of the array.
When the comma operator is used, it assesses each operand in order and provides the value of the final operand. This clarifies why the result is 1.
