                3 Ways of Generating SSH Keys: OpenSSH, OpenSSL and GPG
              
          
    # OpenSSH
# 运行后，要求用户提供密钥文件名
# 然后在当前目录生成两个密钥文件：id_rsa（私钥）和id_rsa.pub（公钥）
$ ssh-keygen -t rsa -b 4096 -C "your.email@service.com"

# OpenSSL
# 生成私钥，然后生成公钥
$ openssl genrsa -out private_key.pem 4096
$ openssl rsa -pubout -in private_key.pem -out public_key.pem

  
## default-parameter-scope.js
// 情况一
let str = 'outer';

function foo(x = () => str) {
  let str = 'inner';
  console.log(x()); // outer
}

foo();

## default-parameter-by-express.js
let x = 99;

function foo(p = x + 1) {
  console.log(p);
}

foo() // 100

x = 100;
foo() // 101

## map-vs-flatmap.js
const map = (array, func) => (
  array.map(func)
);

const flatMap = (array, func) => (
  array.reduce((result, element) => (
    result.concat(func(element))
  ), [])
);

## shape-detction-API.js
// 条形码识别（Chrome 56 支持）
var barcodeDetector = new BarcodeDetector();
barcodeDetector.detect(image)
  .then(barcodes => {
    barcodes.forEach(barcode => console.log(barcodes.rawValue))
  })
  .catch((e) => {
    console.error("Boo, BarcodeDetection failed: " + e);
  });
