Create sample strings based on a regex

npm i --save regex-to-string

const builder = new Builder(/a+ regexp?/)

builder.build()  //   =>   aaaaaaaaaaaa regexp
builder.build()  //   =>   aaaaaa regex
builder.build()  //   =>   aaa regexp
builder.build()  //   =>   aaaaaaaaaaaaaaaaaa regexp
builder.build()  //   =>   aaaaaaa regex
builder.build()  //   =>   aaaaaaaaaa regex

Config
