They are all literal reference constructors the content is mutable.

Please compare the analogue situation in JS where [] and {} explicitly documented as "literal".°

See also Readonly which makes the explicit distinction about overwriting a variable holding an array and protecting the deep content.

Arrays can be created using the literal notation:

let fruits = ['Apple', 'Banana'];

console.log(fruits.length); // 2
console.log(fruits[0]);     // "Apple"
