    }
  }
}

console.log(check(messageUser))

CodePudding user response：

you can use

array.some to check if one entry match a condition
string.includes to check if word is include in string

const keyWords = ["Hello", "hello", "help please", "Help please", "John", "john", "need", "Need"]

var messageUser = "My name is Peter and I need help";

function check(str) {
  return keyWords.some(word => messageUser.includes(word));
}

console.log(check(messageUser))
