understand the use of let. Example let a = 1; if (a == 1) { let a = 2; console.log(a); } console.log(a); Output 2 1 7. BabelJS — Transpile ES6 features to ES5 BabelJS console.log(a); } console.log(a); Transpiled using babel to ES5 "use strict"; var a = 1; if (a == 1) { var _a = 2; console.log(_a); } console.log(a); understand how const keyword is used. Example let a =1; if (a == 1) { const age = 10; } console.log(age); Output Uncaught ReferenceError: age is not defined at :5:13 The above output

1.1. 两种模糊匹配 如果正则只有精确匹配是没多大意义的，比如 /hello/，也只能匹配字符串中的 "hello" 这个子串。 var regex = /hello/; console.log( regex.test("hello") ); // => true 正则表达式之所以强大，是因为其能实现模糊匹配。 而模糊匹配，有两个方向上的“模糊”：横向模糊和纵向模糊。 1.1.1. 横向模糊匹配 页 测试如下： var regex = /ab{2,5}c/g; var string = "abc abbc abbbc abbbbc abbbbbc abbbbbbc"; console.log( string.match(regex) ); // => ["abbc", "abbbc", "abbbbc", "abbbbbc"] NOTE 案例中用的正则是 /ab{2,5}c/g，其中 "a1b"、"a2b"、"a3b"。 其可视化形式如下： 测试如下： var regex = /a[123]b/g; var string = "a0b a1b a2b a3b a4b"; console.log( string.match(regex) ); // => ["a1b", "a2b", "a3b"] 以上就是本章讲的主体内容，只要掌握横向和纵向模糊匹配，就能解决很大部分正则匹配问题。 接下来，我们将具体展开来说。

Calc { constructor() { console.log('Calc constructor'); } add(a, b) { return a + b; } } var c = new Calc(); console.log(c.add(4,5)); ECMAScript 6简介 Calc() { console.log('Calc constructor'); }; ($traceurRuntime.createClass)(Calc, {add: function(a, b) { return a + b; }}, {}); var c = new Calc(); console.log(c.add(4, 5)); return 声明的变量只在它所在的代码块有效。 for 循环的计数器，就很合适使用 let 命令。 for (let i = 0; i < 10; i++) { // ... } console.log(i); // ReferenceError: i is not defined 上面代码中，计数器 i 只在 for 循环体内有效，在循环体外引用就会报错。 下面的代码如果使用 var

import { map } from 'rxjs/operators'; map(x => x * x)(of(1, 2, 3)).subscribe((v) => console.log(`Output is: ${v}`)); When we go to execute the above code in command prompt, using command: node let list1 = [1, 6, 15, 10, 58, 2, 40]; from(list1).max((a,b)=>a-b).subscribe(x => console.log("The Max value is "+x)); From RxJS version 5.5 onwards, we have to use pipe() to execute the operator: 'rxjs/operators'; RxJS 14 from(list1).pipe(max((a,b)=>a-b)).subscribe(x => console.log("The Max value is "+x)); Operators Renamed During restructuring of the packages some of the operators
