Expected:

//// [restParameterWithBindingPattern2.ts]
function a(...[a, b]) { }

//// [restParameterWithBindingPattern2.js]
function a() { }

Actual:

//// [restParameterWithBindingPattern2.ts]
function a(...[a, b]) { }

//// [restParameterWithBindingPattern2.js]
function a() {
    var [a, b] = [];
    for (var _i = 0; _i < arguments.length; _i++) {
        ()[_i - 0] = arguments[_i];
    }
}
