Random Number Generator using Google Apps Script
The provided code defines a function called SUM_OF_SQUARES that calculates the sum of the squares of numbers within a given range. Here's a step-by-step breakdown of the code:
Initialize a variable sum with a value of 0. This variable will store the cumulative sum of the squares.
Convert the range input to a string using the toString() method. This step ensures that the range is treated as a string, even if it was originally a different data type.
Remove any whitespace characters from the string using the replace() method with a regular expression /\s+/g and replacing them with an empty string. This step eliminates any spaces within the string.
Trim any leading or trailing whitespace from the string using the trim() method. This step ensures that any extraneous whitespace at the beginning or end of the string is removed.
Split the modified range string into an array of individual values using the split() method. The values are split using commas as the delimiter.
Iterate over each value in the arr array using the forEach() method.
Within the loop, convert each value to a number by implicitly multiplying it with itself (val * val). This step ensures that the value is treated as a number for the subsequent addition.
Add the squared value to the sum variable.
After iterating through all the values, return the calculated sum as the result of the function.
In summary, the SUM_OF_SQUARES function takes a range of numbers as input, calculates the square of each number within the range, and returns the sum of the squared values. The code ensures that the input range is converted to a string, any whitespace is removed, and each value is squared and added to the cumulative sum.
