ISSUE: Total Pages Calculation Fix for project RMTDEV

[Dev-Dipesh]

Project: rmtdev
Video Number: 158
Video Title: Finish Pagination (Derived State)

ISSUE: In the video, we're calculating the total pages without using Math.ceil().

FIX:
Math.ceil is important here because we want to round up to the nearest whole number. For example, if we have 15 jobs and we want to display 7 jobs per page, we need 3 pages.

15 / 7 = 2.14 // Simple division will set total pages to 2, which will lead to missing the last job

Math.ceil(2.14) = 3 // We need 3 pages to show all 15 jobs

The code is actually correct. You can double check. Because the number totalPages is by is actually not a integer. This is JavaScript, not Java.

 const totalPages = totalJobs / RESULTS_PER_PAGE; 

In Java, we would use the following expression.

int totalPages = (totalJobs + RESULTS_PER_PAGE - 1) / RESULTS_PER_PAGE;
