Javascript program to find the power of any number x^y

Javascript program to find the power of any number x^y. There are you will learn how to find the power of any number x^y in javascript language.

Formula:

r = b ^ y

where:

r = result

b = base value

y = exponent value

There are two ways to implement these formulae:

• By using the default method
• Second, by using Math.pow() function

1. By using the default method

/* Javascript program to find the power of any number */

<script type="text/javascript">
    
    var b, e, r = 1, i = 1;
    
    // b = base
    // e = exponent
    // r = result
    // i = looping incremental
    
    b = 5;
    e = 4;

    // finding power of base value by equiping exponent value    
    while(i <= e)
    {
        r *= b;
        i++;
    }
    
    document.write("Result:: " + b + "^" + e + " = " + r )
    
</script>

Output Screen:

2. By using Math.pow() function

/* Javascript program to find the power of any number by using Math.pow() function */

<script type="text/javascript">
    
    var b, e, r;
    
    // b = base
    // e = exponent
    // r = result
    
    b = 8;
    e = 4;
    
    // finding power of base value by equiping exponent value
    r = Math.pow(b, e);
    
    document.write("Result:: " + b +"^" + e + " = " + r )
    
</script>
