简单的字符串替换不需要正则表达式：

let myString = 'No Status: not enough information to provide one. more research and data-gathering is required.';

let newString = myString.replace('not enough information to provide one. ', '');

console.log(newString);

• 或 * with regex：

let myString = 'No Status: not enough information to provide one. more research and data-gathering is required.';

let newString = myString.replace(/:.*?\./, ':');

console.log(newString);
