Precautions
Syntax format
Cocos Creator 3.0 and Cocos Creator v2.x use a different syntax format.
Cocos Creator 3.0 has full support for ES6 and TypeScript. Therefore, Cocos Creator 3.0 only supports ES6 and TypeScript classes
. In addition, we also support TypeScript syntax hints.
Cocos Creator supports only ES5 classes
.
Please keep this precaution in mind.
