Simplify Your Code with a Simple Trick

Simplify Your Code with a Simple Trick

Use Early Returns

Instead of nesting multiple if statements, try using early returns to simplify your code.

Before

function checkUserPermissions(user) {
  if (user.isAdmin) {
    if (user.hasPermission) {
      // do something
    } else {
      // do something else
    }
    // do something else
  } else {
    // do something else
  }
}

After

function checkUserPermissions(user) {
  if (!user.isAdmin) return;
  if (!user.hasPermission) return;
  // do something
}

By using early returns, you can reduce the complexity of your code and make it easier to read.

Keep your code simple, and your users will thank you!
