JavaScript How to iterate over any array to return the value “true” if any elements are true iterate over array javascript,iterate over array python,iterate over

This question is regarding JavaScript. If the input is any of the following array "hello, hi, yo, or hey", I want the value to return true, but it is only returning false.

I've tried multiple methods like toString(), includes(), etc.

function myFunction() {
  var arr1 = [/hello/i, /\bhi/i, /\bhey/i, /\byo\s/i];
  var b = document.getElementById("input1").value;
  for (i = 0; i < arr1.length; i++) {
    var greeting1 = arr1[i].test(b);
    greeting1.toString()
    document.getElementById("demo").innerHTML = greeting1
  }
}
<input type="text" id="input1">
<button type="submit" onclick="myFunction()">Test</button>
<p id="demo"></p>
Answer:1

You could use Array.prototype.some() to check if at least one of the regular expressions match. I've modified a little bit your code just to give you an example:

function myFunction(value) {
    var arr1 = [/hello/i, /\bhi/i, /\bhey/i, /\byo\s/i];
    console.log(arr1.some(a => a.test(value)));        
}

myFunction('hello');
