lesson 1:
let code = 'console.log("hello world")' eval(eval('code')) // console logs hello world
works as expected
lesson 2:
babeljs is a es6 -> es5 interpreter… for browser compatibility
neat feature to usher developers to use es6, to write code, that has good compatibility when the browser adoption rate could be better- - - - - -
lesson 3:
JS runs on a single thread: not exactly true. Just very recently, I learnt about webworkerIt runs on a separate thread, (non-ui). the disadvantages: webworker has no access to dom, parent, getelementbyid etc. the advantages: it’s non-blocking, and thus useful for cpu intensive processes.
