Reading through the documentation for powershells add-type it seems you can add JScript code to you powershell session.
Firstly is there a decent example of how this is done and secondly can you use this to validate normal javascript code (as I understand JScript is the MS implementation)
This may be a good starting point

Here is a code snippet from the above article:
function Create-ScriptEngine()
{
param([string]$language = $null, [string]$code = $null);
if ( $language )
{
$sc = New-Object -ComObject ScriptControl;
$sc.Language = $language;
if ( $code )
{
$sc.AddCode($code);
}
$sc.CodeObject;
}
}
PS> $jscode = @
function jslen(s)
{
return s.length;
}
@
PS> $js = Create-ScriptEngine JScript $jscode;
PS> $str = abcd;
PS> $js.jslen($str);
