const regex = new RegExp(/^a...s$/); console.log(regex.test('alias')); // true Run Code In the above example, the string alias matches with the RegEx pattern /^a...s$/. Here, the test() method is used to check
==null){// This is necessary to avoid infinite loops with zero-width matchesif(m.index===regex.lastIndex){regex.lastIndex++}// The result can be accessed through the `m`-variable.m.forEach((match,groupIndex)=>{console

Mangling property names is a separate step, different from variable name mangling. Pass --mangle-props to enable it. The least dangerous way to use this is to use the regex option like so: terser example.js -c -m --mangle-props regex=/_$/ This will mangle all properties that end w...

这个针对正则字面量的,为了更好地来解析正则表达式的内容,添加多一个 regex 字段,里边会包括正则本身,以及正则的flags。 复制 interface RegExpLiteral <: Literal {regex: {pattern: string;flags: string;};} 1. 2. 3. 4. 5. 6. Programs 一般这个是作为跟节点的,即代表了一棵完整的程序代码树。
