+ * This function takes a generic expression and detects whether it is an ObjectExpression.
+ * This is used in the context of parsing CommonJS exports to get the value of the property descriptor
+ * when the `exports` object is assigned to `Object.defineProperty`.
+ *
+ * In CommonJS modules, the `exports` object can be assigned to `Object.defineProperty` and therefore
+ * webpack has to detect this case and get the value key of the property descriptor. See the following example
+ * for more information: https://astexplorer.net/#/gist/83ce51a4e96e59d777df315a6d111da6/8058ead48a1bb53c097738225db0967ef7f70e57
+ *
+ * This would be an example of a CommonJS module that exports an object with a property descriptor:
+ * ```js
+ * Object.defineProperty(exports, "__esModule", { value: true });
+ * exports.foo = void 0;
+ * exports.foo = "bar";
+ * ```

+ * @param {TODO} expr expression
+ * @returns {Expression | undefined} returns the value of property descriptor
