To calculate the Rate of Change (ROC) in TypeScript, you can follow these steps:

- Determine the initial value and the final value for the variable you are analyzing. For example, let's say the initial value is 50 and the final value is 70.
- Calculate the difference between the final value and the initial value. In this case, the difference would be 70 - 50 = 20.
- Divide the difference by the initial value. In our example, the ROC would be calculated as (70 - 50) / 50 = 0.4.
- Multiply the result by 100 to get the percentage rate of change. In our example, the ROC in percentage would be 0.4 * 100 = 40%.

So, the rate of change for the variable from 50 to 70 is 40%.
