Why does Eclipse ide get errors when using async await - Semi-colon expected?

Question

JavaScript

I installed the Eclipse IDE for JavaScript Web Developers assembly,
everything works, but it swears at async and await in the code,
displays the "Semi-colon expected" error where these words occur.
The code itself runs without error, like
async function test(){
console.log('test');
}
Where that it is possible to correct in Eclipse that he did not swear?

Answer 1

"Semi-colon expected" = Semi-colon expected. It is necessary to look for what place swears and fix it))
