Difference between array and slice

• array -> are of fixed size used very less when you are working in real systems
• slice -> are of dynamic size and have better performance then normal array, used most in the real systems

Why slices are used more in Go

• i guess because they are dynamic and more realiable to use and efficiency is far better than normal fixed array

What does append() do internally (basic idea)

• i guess you are asking it for the slice
  • Case -> when you have enough space
    • it just add the element at the end simply
  • Case -> when you dont have enough space
    • it create a new array of double size generally and copy the rest of the elements to it and do this process if this case hits

Difference between len and cap

• len -> the number of elements are there in the slice
• cap -> the actual reserved size of the slice
