<cfscript>
function updateUI() {
    writeOutput('Counter: ' & count & '<br>');
    writeOutput('Theme: ' & iif(isDark, 'Dark', 'Light') & '<br>');
}

Demonstrates a simple counter with theme toggling using ColdFusion variables and output tags.

<cfscript>
a = 0;
b = 1;
writeOutput(a & '<br>');
writeOutput(b & '<br>');
for(i=1; i <= 8; i++) {
    c = a + b;
    writeOutput(c & '<br>');
    a = b;
    b = c;
}
</cfscript>

Generates first 10 Fibonacci numbers.

<cfscript>
n = 5;
f = 1;
for(i=1; i <= n; i++) {
    f *= i;
}
writeOutput(f);
</cfscript>

Calculates factorial of a number.

<cfscript>
n = 13;
isPrime = true;
for(i=2; i < n; i++) {
    if(n mod i == 0) {
        isPrime = false;
        break;
    }
}
writeOutput(iif(isPrime, 'Prime', 'Not Prime'));
</cfscript>

Checks if a number is prime.

<cfscript>
arr = [1,2,3,4,5];
sum = 0;
for(i=1; i <= arrayLen(arr); i++) {
    sum += arr[i];
}
writeOutput(sum);
</cfscript>

Calculates the sum of an array of numbers.

<cfscript>
s = 'HELLO';
r = '';
for(i=len(s); i >= 1; i--) {
    r &= mid(s,i,1);
}
writeOutput(r);
</cfscript>

Reverses a string.

<cfscript>
n = 5;
for(i=1; i <= 10; i++) {
    writeOutput(n & ' x ' & i & ' = ' & (n*i) & '<br>');
}
</cfscript>

Prints multiplication table of a number.

<cfscript>
c = 25;
f = (c * 9/5) + 32;
writeOutput(f);
</cfscript>

Converts Celsius to Fahrenheit.

<cfscript>
temp = 80;
thresh = 75;
writeOutput(iif(temp > thresh, 'Alarm: Temperature Too High!', 'Temperature Normal'));
</cfscript>

Simulates an alarm when temperature exceeds a threshold.

<cfscript>
steps = 10;
pos = 0;
for(i=1; i <= steps; i++) {
    if(rand() LT 0.5) {
        pos++;
    } else {
        pos--;
    }
    writeOutput(pos & '<br>');
}
</cfscript>

Simulates a 1D random walk.
