如何修剪单词之间的空格,以及使用javascript后的逗号

Question

我有一个名为name的字符串,我希望修剪一个句子中的单词之间的空格,并在逗号之后修剪空格.我可以在句子的开头和结尾使用trim()修剪额外的空格.
[我正在使用javascript来实现我的代码]

name = '      Barack Hussein       Obama II is an     American politician who served       as the 44th President        of the United States from January 20,    2009,    to January 20, 2017.  

预期产出:

name = ' Barack Hussein  Obama II is an American politician who served  as the 44th President of the United States from January 20, 2009, to January 20, 2017. 

Answer 1

假设剩余的双空格只是一个拼写错误,您可以使用正则表达式匹配一个或多个空格,并用一个空格替换每个空格:

const name1 = '      Barack Hussein       Obama II is an     American politician who served       as the 44th President        of the United States from January 20,    2009,    to January 20, 2017.';
console.log(
  name1.replace(/ +/g, ' ')
);
