You can use an array to store multiple strings!
For example:
var wordArr = ["foo", "bar", "spam", "eggs"];
PS:
klisco1, Use a for loop to check with every word.
for(let i in wordArr) {
if(wordArr[i] == o) {
// o is the value of the input in your case!
alert("You can't use such word!");
}
} // this code needs ES6 support!
Post PS:
klisco1, here it works for me:
