Use getenv with js

[vsantana]

Hi everyone! when I try to compile this code into js (e.g. nim js main.nim)
    
    
    import os
    echo getEnv("USER")
    
    Run

I'm getting the follow error: 
    
    
    .choosenim/toolchains/nim-1.2.2/lib/pure/includes/osenv.nim(97, 16) Error: 
internal error: expr(nkBracketExpr, tyUncheckedArray)
    
    Run

Was this supposed to work?
