Fix #48 (closed)
There are some syntaxes are not supported in IE,
append(), for...of default values for arguments ---> function(array=)
Anyway, IE is very less in use, and MS is not going to support IE anymore in next year, it's not a critical issue, and I feel sorry cannot use ES6 syntax due to IE. I'll leave it to you to decide whether we have the needs to fix it since IE won't be supported in the future.
