JDoodle is a super fast/easy IDE for beginners for a number of programming languages. It is not as advanced as other websites like (repl.it) but I think it is fine for simple tinkering with code. PS: Whoever created the WOT warning about this site was making assumptions based SOLELY on the use of a proxy registrar without evidence of any actual malicious code. I think the warning is a mistake as neither myself nor anyone I know has ever seen any malware or hacks coming from JDoodle.
