Enforce conventional usage of array construction Array construction is conventionally done via literal notation such as `[]` or `[1, 2, 3]`. Using the `new Array()` is discouraged as is `new Array(1, 2, 3)`. There are two reasons for this. The first is that a single supplied argument defines the array length, while multiple arguments instead populate the array of no fixed size. This confusion is avoided when pre-populated arrays are only created using literal notation. The second argument to avoiding the `Array` constructor is that the `Array` global may be redefined. The one exception to this rule is when creating a new array of fixed size, e.g. `new Array(6)`. This is the conventional way to create arrays of fixed length. ### Invalid: ```typescript // This is 4 elements, not a size 100 array of 3 elements const a = new Array(100, 1, 2, 3); const b = new Array(); // use [] instead ``` ### Valid: ```typescript const a = new Array(100); const b = []; const c = [1, 2, 3]; ```
