What is the best way to deduct a variable's previous value from the final value, ensuring that the total value does not surpass a specific limit?

For instance:

let num = 20;
const sub = 6;
const add = 10;
num = num - sub;
num = num + add;
if (num > 20){
    num = 20;
}
console.log("Only 6 was actually added to var num before reaching its maximum value");

Is there a way to adjust the console log to reflect that only 6 was truly added to var num before reaching its limit?

Answer №1

It seems like your question is a bit unclear. Are you looking to keep track of the value of num?

To do so, I suggest using an array:

let log = [];

Before making any changes to num, you can push its current value to the array:

log.push(num);

You can find more information about arrays in JavaScript here.

If you simply want to display the value of a variable in the console, there are multiple ways to do so:

console.log(add, " was added to var num");
console.log(add + " was added to var num");
console.log(`${add} X was added to var num`);

You can learn more about console logging here and template literals here.
