IE11 error in v2.14.0

[jackocnr]

I'm seeing this error:

Expected identifier, string, or number

When I upgrade from v2.13.0 to v2.14.0.

I'm using the following imports from date-fns:

import format from 'date-fns/format';
import parseISO from 'date-fns/parseISO';
import { da, de, es, fr, id, it, ms, nb, nl, pl, pt, ro, sv, tr } from 'date-fns/locale';

Here is a screenshot from IE11 devtools - the error is caused by line 10481.

Let me know if there's anything else I can provide.

I had the same error, here's a temporal solution I used until this is fixed.

Using npm postinstall script. I rewrite the [-1] to '-1'

#!/usr/bin/env sh

replaceLocale()
{
    if test -f "$1" ; then
        echo "Replacing [-1] in '$1'."
        sed -i -e "s%\[-1\]\:%'-1'\:%" $1
        sed -i -e "s%\[1\]\:%'1'\:%" $1
        sed -i -e "s%\[0\]\:%'0'\:%" $1
        echo "Replaced IE 11 incompatible syntax in '$1'"
    else
        echo "'$1' does not exist."
    fi 
}

replaceLocale "node_modules/date-fns/esm/locale/hu/_lib/formatDistance/index.js"
replaceLocale "node_modules/date-fns/locale/hu/_lib/formatDistance/index.js"

You can transpile date-fns with webpack babel-loader.
