In this tutorial, we will discuss the title of the JavaScript Program to substract Two Numbers
In this topic, we are going to learn how to write a program to subtract two numbers in the JavaScript programming language
Subtract of two numbers

JavaScript program for subtracting of two numbers
Program 1
Here, We use the minus(-) operator to find the differences between the given two numbers. The difference between the two numbers 24 and 14 and the output is displayed here
//Caculate subtraction of two numbers in JavaScript
const f_Num=24;
const l_Num=14;
//declare and initaiize two variable
//calculate difference of two numbers
const dif=f_Num-l_Num;
//display the difference of two numbers
console.log('The subtraction of '+f_Num+' and '+l_Num+' is: '+dif);
When the above code is executed, it produces the following result
The subtraction of 24 and 14 is: 10
JavaScript program for subtracting of two numbers using HTML
Program 2
Here, We use the minus(-) operator to find the differences between two numbers. The difference between two numbers 15 and 20 , the output is displayed here
<html>
<head>
<title>Subtraction of two numbers</title>
<script>
var f_Num=15;
var l_Num=20;
var sub=f_Num-l_Num;
document.write("subtraction of "+f_Num+" and "+l_Num+" is: "+sub);
</script>
</head>
<body>
</body>
</html>
When the above code is executed, it produces the following result
subtraction of 15 and 20 is: -5
JavaScript program for subtracting of two numbers using function

<html>
<head>
<title>subtract two numbers</title>
<script>
function subs()//function to subtraction
{
var f_Num,s_Num,dif;
f_Num=Number(document.getElementById("first").value);
s_Num=Number(document.getElementById("second").value);
dif=f_Num-s_Num;
document.getElementById("ans").innerHTML="Difference:"+dif;
}
</script>
</head>
<body>
<p>Enter the first Number:<input type="text" id="first"></p>
<p>Enter the second Number:<input type="text" id="second"></p>
<button >
When the above code is executed, it produces the following result
