In Rust, <code>[10, 20, 30]</code> can be a fixed-size array whose length is part of its type. In Python, the same visual shape creates a mutable <code>list</code>. PHP uses bracket syntax for an ordered map, while JavaScript creates a resizable <code>Array</code> object.</p> <p>The syntax is easy to memorize. The more important distinction is what the value means after it has been created.</p>
