javascript switch Case

Switch Case Statement এর কাজ If...else if স্টেটমেন্ট এর মতোই ।

কিন্তু স্মরণ রাখবেন প্রোগ্রামে If...else if স্টেটমেন্ট এবং switch case statement এর কাজের ধরন ও বৈশিষ্ট্য একরকম হলেও অনেকটা ভিন্ন প্রকৃতির । যেমনIf...else if statement এর ক্ষেত্রে কন্ডিশান হিসাবে ব্যবহার করা হয় Logical বা Relational অপারেটর । কিন্তু Switch statement এর ক্ষেত্রে কোন কন্ডিশান এক্সপ্রেশন ব্যবহার করা হয় না । Switch statement এর ক্ষেত্রে ব্যবহার করা হয় ভ্যারিয়বেল । এই ভ্যারিয়বেল ভ্যালুর উপর নির্ভর করে কোন Case Statement টি এক্সিকিউট হবে ।

নোট : যত খুশি Case লিখতে পারি প্রয়োজন মত ।
