I was wondering what is the better way of writing? Having several variables to show the steps or rather do method chaining?
function count(string) {
const array = string.split("");
return array.filter(element => element === "a").length
}
function count(string) {
return string
...
is there a shorter way to write this code block?
i tried it with arrow functions but it spat back errors and didn't want to work.
function r(){
rx = Math.floor(Math.random()*255)
return rx;
};
function g(){
gy = Math.floor(Math.random()*255)
return gy;...
I have a set of code that calculates how well a templates fits a users details. It's kind of long, so I've cut out all the code that does it's job well and only included the bottle neck and surrounding code. My target here is speed!
A couple of notes on the variables:
Calculated at run time (ch...
I was thinking about a decorator which enable a lambda function to be called through a operation statement, in this example the @ one.
How about this:
def at(l):
class At:
def __rmatmul__(self, arg):
return l(arg)
return At()
Here there is an executable exampl...
My code reviewer tells me to move the let assignment above the guard clause in the following code. That would force a variable declaration and an assignment even in the scenario of the code being stopped by the guard clause.
Why would he think that way ?

I'm using Flask along with Flask-SQLAlchemy and Flask-WTF.
I have a model:
class Trip(db.Model):
id = db.Column(db.BigInteger, primary_key=True)
author_id = db.Column(db.Integer, db.ForeignKey('users.id'), index=True,
nullable=False)
name = db.Column(db.Str...
From my spreadsheet script editor I am using a script to submit data (emails) to the sheet.
In the sheet I have two tabs:
Sheet1: receives the new submitted emails
Sheet2: sorts the emails in Sheet1 in a reverse order based on the Timestamp column so all the time in Sheet2 I have the last subm...
When I try to correct a typo, I get the following error:
Edits must be at least 6 characters; is there something else to improve in this post?
Are typos not worth to correct?
I recently faced an interview question where you have to find minimum needed items from an array that can added together to generate X value.
For example giving:
[1, 9, 2, 5, 3, 10] and the goal is: 13, => it should be [10, 3]
You can't use any number out side of array.
I have tried to sort...

I'll give briefly description, ask some questions and then post whole code.
Open to any opinons and suggestions, thank you.

This is my first working 2sum solver. It works by finding the difference for our target in s to determine if that 2sum exists.
Suppose our target is -5. I start with the first index in s and use subtraction. (-5-(-8) = 3) And the result is 3. The code will check the difference in s. If the dif...
I'm learning to write PHPUnit tests for my Symfony app. Currently, I'm writing tests for one of my service JokeService. I'm trying to test all it's public methods. This is the test file:

I recently had to submit my 12th grade final project in C++, so I decided to make a game engine! That panned out just as you would expect (I am not touching OpenGL until they touch OOP), so I switched and ended up making a project on graph coloring instead!
For context, in the actual project thi...
Project Euler 044
The Python3 solution below returns the answer in less than 1 second. It relies on:
$$P_{(k+n)} - P_k = 3kn + \frac{2n^2}{2} - \frac{n}{2}$$
and:
$$P_{(k+n)} + P_k = 3k^2 + 3kn + \frac{3}{2}n^2 -k - \frac{n}{2}$$
Looking at the first line in the solution() definition, I am ...
i have a interface under development using an object-based approach. Objects should be statically allocated by the application writer (Dynamic memory allocation are not allowed). I want to obfuscate the object data so the application writer can only access the struct members using the provided me...
