有点神秘但做你需要的事情：

A bit cryptic but does what you need:

var source = 'lorem hello foo bar world';
var words = ['hello','red','world','green'];

words = words.map(function(w){ return +!!~source.indexOf(w) });

console.log(words); //=> [1, 0, 1, 0]

+ !!〜转换 indexOf 返回的值的多个布尔表示形式，与：

+!!~ casts a number of the boolean representation of the value returned by indexOf, same as:

return source.indexOf(w) == -1 ? 0 : 1;

但有点短。

注意 indexOf 匹配字符串中的字符串，如果要匹配整个单词，可以使用带有字边界的正则表达式 \b ：

Note that indexOf matches strings within strings as well, if you want to match whole words you can use regex with word boundaries \b:

words = words.map(function(w) {
  return +new RegExp('\\b'+ w +'\\b','gi').test(source);
});
