Funny answer now - the difference is as between car and carpet :)

Java is also an island in Indonesia.

Java code gets compiled to bytecode to be understood by the machine (personal computer/server), Javascript doesn't need to be compiled into bytecode, and it is easily interpreted directly.

Java and Javascript languages use different implementation for inheritance, classical inheritance and prototypal inheritance respectively.

Java features and standards are handled and Implemented by oracle now a days, Javascript features and standards are decided by ECMA and solutions/syntax of these standards implemented by the browser creators (like, Google Chrome, Safari) for us, so we can write a syntax that browsers can understand.

Java was born to replace c++, mainly for computations and write once, run anywhere purposes, Javascript was born to be the scripting language in the browser, that can add behavior to the webpages.

Today - Java is used in mobile app development, IoT, server side programming, Desktop apps, Games. Javascript is used at all of these uses mentioned in Java + it is used in the browser too.

Javascript and java is like Carpet and Car

What is a scheme based language? I heard that JavaScript borrows a lot from scheme and it is great but I have no idea what it means and why it is great.

app.use(async function(ctx) {
  const body = ctx.request.body;
  if (!body.username) ctx.throw(400, '.username required');
  if (!body.password) ctx.throw(400, '.password required');

  ctx.body = { 
    code: 201,
    message: '登陆成功',
    jianCeZhe: '张三',
    jianCeDanWei: "光明农场"
  };
});

Good explanation of differences. -- Yoog
