Definitely, the following way of declaring multiple variables is more efficient:
var variable1 = 5; var variable2 = 3.6; var variable3 = “Amit”;
Suppose you need to add, remove, or update a variable, then you can easily do it.
But with the following method, you need to do more changes. For example, on removing a variable, you need to remove the semi-colon. If it’s the first, then you need to add var to the second variable.
var variable1 = 5, variable2 = 3.6, variable3 = “Amit”
