Is this an efficient way to get the value of Pi, where the limit of j ∝ accuracy?
PI = 0;
for (var j = 1; j < 100; j+=2) PI += (4/j)*((j+1)%4?1:-1);
How can I make my code better?
function generateRandNum(min, max) {
minimum = Math.ceil(min);
maximum = Math.floor(max);
return Math.floor(Math.random() * (maximum - minimum)) + minimum;
}
function generateNewPost(json_data) {
var rand_num = generateRandNum(0, json_data.length)...

I was trying to write some simple data structures to practice ownership concepts in Rust. I'd like a review:
type Link<T> = Option<Box<Node<T>>>;
struct Node<T> {
elem: T,
next: Link<T>,
}
struct List<T> {
head: Link<T>,
}
pub struct Iter<'a, T: 'a> {
next: Option<&'a Node<T>>...

I learned about what is static code analysis. Static code analysis is used for code complexity, duplicaton code, code review..For example.
String[] arr=new String{'A','B','C'};
for(int i=0;i<arr.length();i++)
{
}
//here length() is a inbuilt function. so It will execute 3 times
int len=array.l...
