So, basically I'm working with string manipulation for a chatbot. When it returns a string from a message, I'm just checking if there's an specific word on it:
let msg = 'how are you?' //Message example
let words = msg.split(' ') //Words spliting
if ('are' in words) {} //This is where I'm having the problem
I know that in works for when I check a number inside of an array, but it doesn't seem to work with strings. Is there a different way to call it when it's about strings? I could do the checking using a loop, then a if (words[i] === 'are') {}, but I'd like to avoid that, if possible.
You can use includes:
if(words.includes('are')) { }
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes
You can use words.includes("are"). Check the live demo:
let msg = 'how are you?' //Message example
let words = msg.split(' ') //Words spliting
console.log(words);
if (words.includes("are")) {
console.log('exist');
} else {
console.log('not exist');
}
