What is the meaning of const variable =[0] ? In js

variable is assigned with an array containing 0 (zero) digit

Ok we can also specify using fill method also right?

Yes, but in this example using .fill() method seems like an overkill

Ok thanks for the info What is the difference of declaring empty array over this 0?

SScriptyChris

I don't understand your question 😐 [] is an empty array and [0] is an array with zero inside

Ok so initialising with 0 and then pushing the new element will it over rite correct that 0 inside it

No, using .push() doesn't override anything in an array - it adds new value to the end of that array So if you used .push(2) to your variable then you would have array looking like this [0, 2]
