Because arrays in JS are reference values, so when you try to copy it using the = it will only copy the reference to the original array and not the value of the array. To create a real copy of an array, you need to copy over the value of the array under a new value variable. That way this new array does not reference to the old array address in memory.java exception handling

Thanks for sharing this helpful guide on JavaScript array copying! Understanding how to effectively copy arrays is a fundamental skill for any JavaScript developer. It's crucial for preventing unintended side effects when working with arrays.

On a side note, while the topic of 'sad whatsapp dp' may not directly relate to array manipulation, it's essential to prioritize mental health. If you or someone you know is feeling down, consider seeking support from friends, family, or professionals. Let's foster a positive and supportive environment both in our coding journeys and personal well-being. Keep coding and take care!
