从带有空格的字符串中删除单词

Question

• I want to remove word from string including white spaces.
• For example if the string is 'dog cat cow' and you remove 'dog' it will return 'cat cow' .
• If you want to remove 'cat' it would return 'dog cow' . It need to be removed white spaces before or/and after word also.

Answer 1

To remove a particular word from a string along with whitespaces you can use this following function

function removeWord(sentence, word){
    sentence=sentence.split(" ").filter((item)=>{return item!=word}).join().replace(","," ");
    return sentence;
}

Answer 2

Could be done like this:

var str = "dog cat cow";
var word = 'cat';

console.log(replace(str, word));

function replace(str, word){
  str = str.replace(word, ""); // removing chosen word
  str = str.replace(/\s/g,''); //  removing whitespace
  return str;

}

Not the smallest solution but simplest imo.
