reduce to subtract in javascript

To perform subtraction in JavaScript, you can use the '-' operator.

Here's an example:

index.tsx
let num1 = 10;
let num2 = 5;
let result = num1 - num2;
console.log(result); // Output: 5
89 chars
5 lines

In the example above, we declare two variables num1 and num2 and then subtract num2 from num1 using the '-' operator. The result is stored in the result variable, which we then print to the console using console.log().
