A better way to handle if statements in JavaScript #shorts

Welcome to Coding Frontier,
Instead of writing multiple if-else statements to set a variable based on different conditions, you can use a lookup map (or object) where the keys are the conditions and the values are the results. This makes your code cleaner, easier to read, and more efficient.
---------another example:---------
const dayMap = {
'Monday': 0,
'Tuesday': 1,
'Wednesday': 2,
// Add other days here...
};

const dayNumber = dayMap[day] !== undefined ? dayMap[day] : -1;
// -1 as fallback for unknown days
