I'm a beginner when it comes to JavaScript and I need help setting a maximum value of 50% of the selling price. Can someone offer guidance?
The fields I have are called "sale_price" and "discount".

What is the best way to use JavaScript to limit and adjust the discount amount so that it never exceeds 50% of the selling price?
If you're looking for a way to handle pricing conditions in JavaScript, consider using an if/else statement. Check out the documentation here for more info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/if...else
Here's a basic example:
if(sale_price < (normal_price * 0.5)) {
var something = (normal_price * 0.5)
} else {var something = sale_price}
Alternatively, you can use a ternary operator for a more concise approach. Learn about it here:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Conditional_operator
sale_price < (normal_price * 0.5)?
sale_price = (normal_price * 0.5):
sale_price
Consider the type of variable the sale_price is when choosing your method. If it's constant, opt for an if/else statement. If it varies, go with a ternary operator.
I hope this explanation helps!
