Bug Report
Current Behavior
The commonjs and amd plugins create invalid throw new Error('"' + "foo" + '" is read-only.'); statements in the output when there is an import with the same name as used in the destructuring even though it's shadowed by a function parameter.
Input Code
import { foo } from "./x";
function test(foo) {
console.log(foo);
[foo] = [1];
({foo} = { foo: 1 });
console.log(foo);
}
test(0);Output:
"use strict";
var _x = require("./x");
function test(foo) {
console.log(foo);
[foo] = ([1], function () {
throw new Error('"' + "foo" + '" is read-only.');
}());
({
foo
} = ({
foo: 1
}, function () {
throw new Error('"' + "foo" + '" is read-only.');
}()));
console.log(foo);
}
test(0);Expected behavior/code
No Error's in output, like this when the import name is changed:
"use strict";
var _x = require("./x");
function test(foo) {
console.log(foo);
[foo] = [1];
({
foo
} = {
foo: 1
});
console.log(foo);
}
test(0);Babel Configuration (.babelrc, package.json, cli command)
