See Typescript - Type Assertion (angle-bracket or as)


Typescript borrows cast syntax from Closure. This lets you cast types to other types by adding a @type tag before any parenthesized expression.

 * @type {number | string}
var numberOrString = Math.random() < 0.5 ? "hello" : 100;
var typeAssertedNumber = /** @type {number} */ (numberOrString)
