Arrays start at index 0

Declaration

names = ["Krish", "Kultiversan K", "K"]

Accessing

names[0] // "Krish"

Assigning

names[0] = "Karuto"

Appending

names = append(names, "Hellooo")

Deleting

names = append(names[:2], names[3:]...)

Tips

Tip: While defining variable, You can use ... to let the compiler count the size for you

Note: While defining variable, if is not specified, it is unbounded

Note: When you use arr[0:3] you get the elements including index 0 to index 3, excluding index 3 (so 0, 1, 2)
