IE11 Issue around Symbols #834

Closed paulmowat closed 4 years ago

paulmowat commented 4 years ago

Hi.

Think I've found a issue in IE11 while updating my projects dependencies.

Looks like

mobx4 + mobx-react6.1.5 => success mobx4 + mobx-react6.1.7 => fail

From what I can tell it looks like a issue to do with symbols.

On debugging it seems to be coming from src/utils/utils.ts in the following code

function createSymbol(name) { if (typeof Symbol === "function") { return Symbol(name); }

const symbol = __$mobx-react ${name} (${symbolId}); symbolId++; return symbol; }

Getting a invalid character error at "const symbol = __$mobx-react ${name} (${symbolId});"

Thanks

Paul

Thanks for the report. We have changed the way how the module is built and haven't considered ES5 for bundling. I will fix that soon.
