below javascript code will check if the string contains a specific word or not:
var str = "This is the string where we will check if our word exists.";
var str_pos = str.indexOf("word");
if (str_pos > -1) {
    document.getElementById("myId").innerHTML = "The specific word exists";
} else {
    document.getElementById("myId").innerHTML = "The specific word doesn't exist";
}

The includes() method determines whether a string contains the characters of a specified string.

This method returns true if the string contains the characters, and false if not.

Note:
The includes() method is case sensitive.
The includes() method is not supported in IE 11 (and earlier versions).
Eg.:
var str = "Hello world, welcome to the universe.";
var n = str.includes("welcome");
document.getElementById("demo").innerHTML = n;
