In my app, I have configured Babel to add Core-JS polyfills, but it seems to be adding unnecessary polyfills.
Im using browserlist > 1%
and it's including require("core-js/modules/es.array.concat");
among other Core-JS imports that don't seem necessary. I checked and it's because of IE11, but IE11 does support string concatenation with +
, so this import doesn't seem necessary.
Is there a way to not allow adding these polyfills while still supporting at least IE11?
Assuming you are using preset-env you can exclude them directly with an array of excluded modules.
...
"targets" : "browserlist > 1%",
"exclude": [
"es.array.concat",
],
