The bad parts are there, but as of today it's a very powerful language that runs on every browser (hence every computer in practice?) with massive community support.
Oooh, there's many more computers around you than you think ;-) Nearly every modern piece of electronics. Many don't run browsers. For instance your washing machine has an OS, but it probably doesn't run Javascript. Same goes for your car, washing machine, dishwasher, microwave, central heating system, stereo/hifi, etc. And of course the more obvious "non-PC computers" like routers, printers, scanners, TV (might actually run JS if it's "smart" and has a browser), computer monitor and who knows what else. Coffee machine. The "fancier" it is (for a rather low barrier of "fancy"), the more likely it is to have a chip in it that runs some firmware/OS something, equal in power of what people ran as desktop personal computers a few decades ago.
