So False

Basically if you are programmer, learning a new language is just like opening manual and reading commands (in most cases). So if you know one scripting lanaguage like Ruby, you'll be able to code in JavaScript as well (after short training with manual). Also if you know C#, you'll feel familiar with Java, because these are similar. Personally, my main language right now is JavaScript, because it's been well developed last years and nowadays you can program even desktop or mobile applications using this language and frameworks like NodeJS, Electron, React Native. I also know C# but I use it mainly for playing with Unity. Have touched C++, Python and Java while ago, but I don't use them right now. With JavaScript I obviously also use HTML 5 and CSS 3 (sometimes pug and sass, but I'm still not convinced for those).
