var name = true;
typeof name; // "string", not "boolean"
<script>
var _value = "test value";
Object.defineProperty(window, "testName", {
get: () => _value,
set: (value) => { _value = String(value) },
});
</script>
<script>
var testName = {};
// prints [object Object] string
console.log(testName, typeof testName);
var name = {};
// prints [object Object] string
console.log(name, typeof name);
</script>
Other properties have the same behavior, for example `status`.
Note: there's also LegacyUnforgeable which has similar behavior: https://webidl.spec.whatwg.org/#LegacyUnforgeable
Even if you're not using modules, using an IIFE avoids all this by making your variables local instead of having them define/update properties on the global.
name = {first: "Jane", last: "Doe"}
I must have never used "name" as a name for a global variable or just for ones that were strings.
