js常用工具函数之连字符-与驼峰转换方法

查看vue2源码：src\shared\util.js

1. 连字符-转驼峰

const camelizeRE = /-(\w)/g
export const camelize = (str: string): string => {
  return str.replace(camelizeRE, (_, c) => c ? c.toUpperCase() : '')
}

2. 驼峰转连字符-

const hyphenateRE = /\B([A-Z])/g
export const hyphenate = (str: string): string => {
  return str.replace(hyphenateRE, '-$1').toLowerCase()
}
