What happens with negating an array

What happens with negating an array?

When you negate an array in JavaScript, it is first converted to a primitive value, which is true when the array is non-empty and false when the array is empty. Negating it results in false for non-empty arrays and true for empty arrays.

Example:

let arr = [1, 2, 3];
console.log(!arr);  // Output: false
arr = [];
console.log(!arr);  // Output: true
