📦 Macro To Get Array Size Of Any Data Type In C 📦 The following macro will help you in getting the size of an array of any data type. It works by dividing the length of the array to the size of its field. 💡 Code:

#define num(x) (sizeof (x) / sizeof (*x)) 

int  _tmain() {
   int numbers[10] = 
       {1,1,1,1,1,1};

   char *chars[20] =
       {"","","","","","","","",""};

   printf("Size of numbers[10] is %d\n", 
       num(numbers));

   printf("Size of chars[20] is %d\n",
       num(chars));
}

Output:

  Size of numbers[10] is 10 

  Size of chars[20] is 20

JavaScript Clean Code 🛠 Functions should do one thing 💡 Bad :

function emailClients(clients) {
  clients.forEach((client) => {
    const clientRecord = database.lookup(client);
    if (clientRecord.isActive()) {
      email(client);
    }
  });
}

Good :

function emailActiveClients(clients) {
  clients
    .filter(isActiveClient)
    .forEach(email);
}

function isActiveClient(client) {
  const clientRecord = database.lookup(client);
  return clientRecord.isActive();
}

🖼 Rescale Image In Java 🖼 An image can rescaled using AffineTransform. First of all, Image Buffer of input image is created and then scaled image is rendered. ✔️

BufferedImage imgSource = 
   ImageIO.read(new File("myImage.jpg"));

BufferedImage imgDest = 
   new BufferedImage(100, 100,
   BufferedImage.TYPE_INT_RGB);

Graphics2D g2d = imgDest.createGraphics();

AffineTransform affinetransformation =
   AffineTransform.getScaleInstance(2, 2);

g2d.drawRenderedImage(imgSource,
    affinetransformation);

ImageIO.write(imgDest, "JPG", 
   new File("outImage.jpg"));

JavaScript Clean Code 🛠 Don't add unneeded context 💡 If your class/object name tells you something, don't repeat that in your variable name. Bad :

const Car = {
  carMake: 'Honda',
  carModel: 'Accord',
  carColor: 'Blue'
};

function paintCar(car) {
  car.carColor = 'Red';
}

Good :

const Car = {
  make: 'Honda',
  model: 'Accord',
  color: 'Blue'
};

function paintCar(car) {
  car.color = 'Red';
}

setTimeout(blastOff, 86400000);

Good :

// Declare them as capitalized `const` globals.
const MILLISECONDS_IN_A_DAY = 86400000;

setTimeout(blastOff, MILLISECONDS_IN_A_DAY);
