Implement ECMA-402 2.0 13.4.1 Array.prototype.toLocaleString([locales [, options ]]) http://ecma-international.org/publications/standards/Ecma-402.htm This definition supersedes the definition provided in ES2015, 22.1.3.26.
Note that the list separator is implementation defined. The ICU library does not appear to have a way to get the list delimiter by locale. List pattern data exists in the CLDR, but it may not yet be worth the effort to try to extract the delimiter from patterns for each locale. Currently Firefox and Chrome just use ','.
