npm add --save-dev eslint
node_modules/.bin/eslint
Just use nodemon instead of node to run your code, and now your process will automatically restart when your code changes.
npm install -g nodemon
Do a global search for non-digit characters:

REACT
wireframe : Wireframe 是一種低保真度的設計原型,在去除所有視覺設計細節之下,進行頁面結構、功能、內容規劃。初次接觸Wireframe的人會非常不習慣這種呈現方式,頁面上只有方框和文字,沒有圖片和色彩。繪製Wireframe的目的在於確認每一個頁面的構成,重點在於畫面上要呈現什麼內容、而不是看起來漂不漂亮。
Sketch: CSS
html: hard-code the page
JSX:
5
import React, { Component } from ‘react’;
class Main extends Component {
render (){
return (
</Main>
)
}
}
export default Main;

Javascript Prototype
https://blog.techbridge.cc/2017/04/22/javascript-prototype/
function Person(name, age) { this.name = name;
this.age = age;
}
Person.prototype.log = function () {
console.log(this.name + ', age:' + this.age);
}
var nick = new Person('nick', 18);
// 這個剛講過了,nick.__proto__ 會指向 Person.prototype
console.log(nick.__proto__ === Person.prototype) // true
// 那 Person.prototype.__proto__ 會指向誰呢?會指向 Object.prototype
console.log(Person.prototype.__proto__ === Object.prototype) // true
// 那 Object.prototype.__proto__ 又會指向誰呢?會指向 null,這就是原型鍊的頂端了
console.log(Object.prototype.__proto__) // null
console.log(global)
zero, empty string, null, false, undefined : these are 5 values return false in JS
false and nil: ruby return nil ( ruby way: puts ‘poop’ unless nil )
