We are required to write a JavaScript function that takes in two numbers, say, a and b and returns the total number of prime numbers between a and b (including a and b, if they are prime). For example − If a = 2, and b = 21, the prime numbers between them are 2, 3, 5,...
Run Code Output Enter a positive number: 23 23 is a prime number. In the above program, the user is prompted to enter a number. The number entered by the user is checked if it is greater than 1 using if...else if... else statement. 1 is considered neither prime nor composite. ...

This same code can be applied in any languages likePython,GoLang,Java,PHP,Node.js,Javascript,C,C++,.NET,Rust, etc with the same logic and have performance benefits. It is pretty fast based on the number of iterations needed. Performance time checks were not consistent across languages (in ...
And in previous code, I only divided into the already found prime numbers. It is possible that the overhead of organizing an array of found prime numbers exceeded the savings from a reduction in the number of divisions. https://code.sololearn.com/cBF6i9cbOh3c/?ref=app 20th Jan 2018, 9...
