array as an extension of a regular variable that stores a single value

Question

I'm learning the basics of programming. And I thought about a thing.Namely: this is a board:

var array = [1,2,3,4,5];

this array is a set of such single variables:

let a = 1;
let b = 2;
let c = 3;
let d = 4;
let e = 5;

And this board

var array = [1,2,3,4,5];

is the set of these variables

let a = 1;
let b = 2;
let c = 3;
let d = 4;
let e = 5;

I would like to ask if the board

var array = [1,2,3,4,5];

written in the form of one variable as above is the same as such a single variable? In other words, this or that:

var array = [1,2,3,4,5];

is it the same as this?

let a = 1;
let b = 2;
let c = 3;
let d = 4;
let e = 5;
