In computer programming, array slicing is an operation that extracts a subset of elements from an array and packages them as another array, possibly in a different dimension from the original Array (data structure) in computer science, an array is a data structure consisting of a collection of elements (values or variables), of same memory size, each identified by at least one array index or key, a collection of which may be a tuple, known as an index tuple String interpolation is an alternative to building string via concatenation, which requires repeat quoting and unquoting

[2] or substituting into a printf format string, where the variable is far from where it is used.
A string is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding
More general, string may also denote a sequence (or list) of data other than just characters. Array programming primitives concisely express broad ideas about data manipulation The level of concision can be dramatic in certain cases This is a comparison of data serialization formats, various ways to convert complex objects to sequences of bits
It does not include markup languages used exclusively as document file formats. Depending on the language, array types may overlap (or be identified with) other data types that describe aggregates of values, such as lists and strings Array types are often implemented by array data structures, but sometimes by other means, such as hash tables, linked lists, or search trees.
