<div class="desc"><p><code>new</code> constructs a heap value and returns a reference to it. <code>new Record { field: value, … }</code> allocates a property (or struct) record, filling any omitted fields with their declared defaults; <code>new []T</code> allocates an empty growable slice of element type <code>T</code>, ready for <code>List.push</code>. Because both are references, passing one around shares the same underlying object. Use <code>new</code> for standalone data your code holds directly — as opposed to <code>spawn</code>, which creates a full ECS entity the world tracks and queries.</p></div>
