问TypeScript操作符优先级表(或者类型断言的优先级是多少？)

EN

interface SomeType {
    name: string;
    id: number;
}

var x = {};

var a: SomeType = <SomeType> x;

// Note, when brackets do not affect 
// type assertions they will be left in the output
var b: SomeType = <SomeType> (x);

// When brackets affect type assertions,
// they are erased along with the type information
var c: SomeType = (<SomeType> x);

// Two errors:
// - SomeType is not assignable to d
// - Property id does not exist on x
var d: number = <SomeType> x.id;

// Brackets are useful here:
var e: number = (<SomeType> x).id;

// More complex example
var func = () => {
    return x; // return type is {}
};
var f: SomeType = <SomeType> func();
