 ## Usage
 
 The **Context** object is created in a **featureAbility** and returned through its [getContext](js-apis-ability-featureAbility.md#featureabilitygetcontext) API. Therefore, you must import the **@ohos.ability.featureAbility** package before using the **Context** module. An example is as follows:
 
 ```ts
 import featureAbility from '@ohos.ability.featureAbility';
-let context = featureAbility.getContext();
