    Rule Details

    Disallow generic Array constructors.

    Use of the Array constructor to create arrays is generally discouraged in favor of array literal notation because of the single-argument pitfall and because the Array global may be redefined.

    The rule allows single-argument calls since they are commonly used to create arrays with a specific size.

    Examples of incorrect code for this rule:

    new Array();
Array();
new Array(x, y);
Array(x, y);
new Array(0, 1, 2);
Array(0, 1, 2);

    Examples of correct code for this rule:

    [];
[x, y];
[0, 1, 2];
new Array(500); // single argument creates array with size
Array(someOtherArray.length);
new Array<Foo>(); // TypeScript generic syntax
new Array<Foo>(1, 2, 3);
