javascript箭头函数连写是什么意思?一直不太理解,请大佬说详细一点,代码如下:
let CURRENT = 'NULL';const renderAuthorize = Authorized => currentAuthority => { //这一行的箭头函数连写是什么意思? if (currentAuthority) { if (typeof currentAuthority === 'function') { CURRENT = currentAuthority(); } if ( Object.prototype.toString.call(currentAuthority) === '[object String]' || Array.isArray(currentAuthority) ) { CURRENT = currentAuthority; } } else { CURRENT = 'NULL'; } return Authorized; };export { CURRENT };export default Authorized => renderAuthorize(Authorized);
问题就是第2行代码的箭头函数连写,它是什么意思?
