以leetcode 20为例

0.首先编写代码

function isValid(s: string): boolean {let stack: string[] = []for (let index = 0; index < s.length; index++) {let x: string = s[index]debuggerswitch (x) {case '(':stack.push(')')breakcase '[':stack.push(']')breakcase '{':stack.push('}')breakdefault:if (stack.pop() !== x) {debuggerreturn false}break}}return stack.length === 0
}const str1: string = '({{}}{}[])'
const str2: string = '({{[}{]}}[])'
const str3: string = '({{}}{}[]])'
console.log(isValid(str1)) //true
console.log(isValid(str2)) //false
console.log(isValid(str3)) //false

2.编译ts文件,运行js文件

PS C:\Desktop\软件开发\编程\ts-leetcode-hot100\Stack05\VaildBracket20> tsc .\VB20.ts
PS C:\Desktop\软件开发\编程\ts-leetcode-hot100\Stack05\VaildBracket20> node .\VB20.js
true 
false
false

3.在代码中添加断点（上边的源码中加过了），并运行调试器

PS C:\Desktop\软件开发\编程\ts-leetcode-hot100\Stack05\VaildBracket20> node --inspect-brk .\VB20.js
Debugger listening on ws://127.0.0.1:9229/a32c1233-13d9-4de6-83aa-540fb4227c8d

 4.（谷歌）浏览器中输入

127.0.0.1:9229/a32c1233-13d9-4de6-83aa-540fb4227c8d

 5.在开启一个窗口输入

chrome://inspect

稍等一会，点击

6.开始调试
