Sap Web Ide Shows Errors About Es6+ Features

for (var items in _selectedContexts) { var downloadModel = __parsed[__parsed[items].toString().split('/')[1]][__parsed[items].toString().split('/')[2]]; var length = downloadMo

Solution 1:

Yes, you can ignore the message as long as your target browser supports the object. Uint8Array was added to a somewhat newer JS specification (ECMAScript 2015 aka. ES6). In order to make Web IDE understand and parse ES6, add es6 to the eslint environment settings:

1. Go to Project settings > Code Checking > JavaScript
2. Expand the Validator Configuration panel
3. Add "es6": true to the env object:

   "env": {
     "es6": true,
     "...": "..."
   },
   

   This will edit the internal .eslintrc file accordingly.
4. Save the settings.
