Solution Review: Counting Population
Explore how to implement nested for loops in JavaScript to iterate through a two-dimensional array. Learn to apply conditional checks on object properties to sum population values where temperature is less than or equal to 10 degrees Celsius. This lesson deepens your understanding of loops, array indexing, and conditional statements in JavaScript.
We'll cover the following...
Solution
After setting up loops to iterate the entire two-dimensional array, the solution relies on visualizing the array and ensuring that correct indices are accessed. First create nested loops to iterate the given two-dimensional array. Set terminating conditions to the size of the arrays so that no invalid index is accessed. After setting it up, access each object. Since the problem requires us to take the sum of population with temperature less than or ...
