Multi-case - chained operations This is an example of a multiple-operation sequential switch statement, where, depending on the provided integer, you can receive different output. This shows you that it will traverse in the order that you put the case statements, and it does not have to be...
如果作为一个函数(不带有运算符 new)调用时,Boolean() 只将把它的参数转换成一个原始的布尔值,并且返回这个值,如果省略 value 参数,或者设置为0、-0、null、""、false、undefined或NaN,则该对象设置为 false。否则设置为 true(即使 value 参数是字符串false)。
case 'brinjal': case 'potato': default: console.log('This is not a fruit.'); } When you run the above-written code, you will get the output as shown below: >“This is a fruit.” Like an example shown above, we can use the switch statement for multiple cases making our work easi...

AST 的用途很广,IDE的语法高亮、代码检查、格式化、压缩、转译等,都需要先将代码转化成 AST 再进行后续的操作,ES5 和 ES6 语法差异,为了向后兼容,在实际应用中需要进行语法的转换,也会用到 AST。AST 并不是为了逆向而生,但做逆向学会了 AST,在解混淆时可以如鱼得水。
