Uncaught ReferenceError: functionis not defined error, why?

Question

I have been trying my hands on javascript and it works but suddenly has stopped working ie js functions are not getting called. I have placed both .js and html file on desktop but still not working.

Error:

Uncaught ReferenceError: funcLoadImage is not defined
    at HTMLButtonElement.onclick

and this error could be for any function i am calling.

JS:

function funcLoadImage() {
  document.getElementById("img1").src = "https://upload.wikimedia.org/wikipedia/commons/3/36/Hopetoun_falls.jpg"
}

function funcMath(type, data) {
  if (type == 1) {
    document.getElementById("img1").alt = 'Type 1'
  }

  if (type == 2) {
    document.getElementById("img1").alt = 'Type 2'
  }
}

funtion funcDate() {
  document.getElementById("img1").alt = 'date add'
}

Html Code:

<!DOCTYPE html>
<html>
<head>

</head>
<body>

<img id="img1" src="" alt="No image loaded" width="50%" height="50%"/>
<button id="btn1" width="20%" height="20%" onclick='funcLoadImage()'>Load Image</button>
<button id="btn2" width="20%" height="20%" onmouseover="this.style.width='60%'" onmouseout="this.style.width='20%'">Write Doc</button>
<button id="btn3" width="20%" height="20%" onclick='funcMath(1,4)'>Calculate</button>
<button id="btn4" width="20%" height="20%" onclick='this.innerHTML=Date()'>Display Date</button>

Try this.............

 function funcLoadImage() { document.getElementById("img1").src = "https://upload.wikimedia.org/wikipedia/commons/3/36/Hopetoun_falls.jpg"; } function funcMath(type, data) { if (type == 1) { document.getElementById("img1").alt = 'Type 1'; } if (type == 2) { document.getElementById("img1").alt = 'Type 2'; } } function funcDate() { document.getElementById("img1").alt = 'date add'; }

 <!DOCTYPE html> <html> <head> </head> <body> <img id="img1" src="" alt="No image loaded" width="50%" height="50%"/> <button id="btn1" width="20%" height="20%" onclick='funcLoadImage()'>Load Image</button> <button id="btn2" width="20%" height="20%" onmouseover="this.style.width='60%'" onmouseout="this.style.width='20%'">Write Doc</button> <button id="btn3" width="20%" height="20%" onclick='funcMath(1,4)'>Calculate</button> <button id="btn4" width="20%" height="20%" onclick='this.innerHTML=Date()'>Display Date</button> <p> </p> <script type="text/javascript" src="script1.js"></script> </body> </html>
