Pointer to array: the number of elements in *v (same as len(v)). The cap built-in function returns the capacity of v, according to its type:Īrray: the number of elements in v (same as len(v)). Result of append, often in the variable holding the slice itself:Īs a special case, it is legal to append a string to a byte slice, like this: If it does not, a new underlying array will be allocated.Īppend returns the updated slice. It has sufficient capacity, the destination is resliced to accommodate the The append built-in function appends elements to the end of a slice. Var nil Type // Type must be a pointer, channel, func, interface, map, or slice type func append ¶ func append(slice Type, elems. Pointer, channel, func, interface, map, or slice type.
