In the above code, we have two strings saved in two variables. We want to add the numbers in the string, so we replace the commas with thereplace()method. After the replacement, we convert the string to a float using theparseFloat()function to preserve any decimal point in the string....
This function generates a range of numbers of the desired length and maps it to a random element of the letters string, then concatenates all of the elements together to form a single string. The randomElement() method selects a random character from the letters string, and the reduce method...
