# valid-lazy

Ensures that definitions and uses of properties on the `lazy` object are valid.
This rule checks for using unknown properties, duplicated symbols, unused
symbols, and also lazy getter used at top-level unconditionally.

## Examples of incorrect code for this rule

```js
const lazy = {};
if (x) {
  // Unknown lazy member property {{name}}
  lazy.bar.foo();
}
```

```js
const lazy = {};
ChromeUtils.defineESModuleGetters(lazy, { foo: "foo.sys.mjs"});

// Duplicate symbol foo being added to lazy.
ChromeUtils.defineLazyGetter(lazy, "foo", () => {});
if (x) {
  lazy.foo3.bar();
}
```

```js
const lazy = {};
// Unused lazy property foo
ChromeUtils.defineESModuleGetters(lazy, { foo: "foo.sys.mjs"});
```

```js
const lazy = {};
ChromeUtils.defineESModuleGetters(lazy, { foo: "foo.sys.mjs"});
// Used at top-level unconditionally.
lazy.foo.bar();
```

## Examples of correct code for this rule

```js
const lazy = {};
ChromeUtils.defineLazyGetter(lazy, "foo1", () => {});
ChromeUtils.defineESModuleGetters(lazy, { foo2: "foo2.sys.mjs"});

if (x) {
  lazy.foo1.bar();
  lazy.foo2.bar();
}
```
