Should i use let or const in vue 3 ref variables?

Question

I am creating a new Vue 3 project and i saw many people online declaring refs like this.
const myVariable = ref(false)

Why are we using const all of a sudden in Vue 3?
I get that refs wrap them in some way to make them editable but i still don't get why not declaring them like this:
let myVariable = ref(false)

I know it may sound a foolish question for Vue 3 devs but i cannot understand the reason behind changing values to constants .

During the meanwhile i am using the const declaration in composition API but i'd like to acknowledgwe the reason behind

Answer 1

it's preferences but the argument why const is used is when the value is not changing eg:

const name = 'John';

// Shouldn't work.
name = 'Bill';

With ref() , you don't replace the variable but the property

const name = ref('John');

name.current = 'Bill';

Here's how eslint explains it:

If a variable is never reassigned, using the const declaration is better.

const declaration tells readers, “this variable is never reassigned,” reducing cognitive load and improving maintainability.
