Should you use a switch case or an if-else statement?

if-else Statement

Determine the Season

const month = 7;

if (month >= 3 && month <= 5) {
  console.log("Spring");
} else if (month >= 6 && month <= 8) {
  console.log("Summer");
} else if (month >= 9 && month <= 11) {
  console.log("Autumn");
} else {
  console.log("Winter");
}

The if-else statement is a fundamental construct for conditional decision-making. It provides flexibility in creating conditions and executing code blocks based on those conditions.

• Flexibility: if-else is highly versatile, allowing for complex conditions and multiple branches, making it suitable for a wide range of decision-making scenarios.
• Readability: if-else statements are intuitive, as they mirror the way humans think about conditional logic.
• Default Handling: You can provide a default case (the else part) to handle situations where no conditions are met.

Switch Case

const day = 3;
let dayName;

switch (day) {
  case 1:
    dayName = "Sunday";
    break;
  case 2:
    dayName =…
