| The Fift stack can contain values of the following types: | ||
|
|
||
| | | | | ||
| | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | ||
| | `Integer` | A TVM signed 257-bit integer. | | ||
| | `Cell` | A [TVM cell](/foundations/serialization/cells) for persistent data storage on TON Blockchain. A cell consists of up to `1023` data bits and up to `4` references to other cells. | |

can we add column headers Type | Description, like in tvm/overview.mdx?
languages/fift/types.mdx
Outdated
| | `Slice` | A TVM slice is a read-only view of a TVM cell that allows sequential access to the cell's data and references. A cell can be converted into a slice, extracting stored bits and references without modifying the original cell. | | ||
| | `Builder` | A TVM builder is used to construct a cell by adding data and cell references. | | ||
| | `Null` | The TVM Null type has exactly one value `null`. In Fift, `null` is mostly used to initialize `Box`'es, hashmaps and lists. Usually denoted by `⊥`. | | ||
| | `Tuple` | A tuple is an ordered collection of values of any of the Fift types in this list, where each value is not necessarily of the same type. Tuples can be used to represent values of arbitrary algebraic data types and Lisp-style lists. | |

maybe keep a short description (for Tuple) in the table and move algebraic types and Lisp list details into text below.

| - Word list: A partially created list of word references, used for creating an execution token. See section for Blocks in the Control Flow page. See also Section [4.7](https://localhost:3000/languages/fift/whitepaper#4-7-creating-and-manipulating-word-lists) in the whitepaper for a list of words that create and manipulate word lists. | ||
| - Execution token: Fift code that can be executed and manipulated on the Fift stack. See section for Blocks in the Control Flow page for more details. | ||
| - Fift hashmap: A hashmap specific for Fift. These hashmaps are not represented as cells, contrary to TVM hashmaps. Refer to Fift hashmaps page for more details. As a comparison with TVM hashmaps, refer to Section [6.3](https://localhost:3000/languages/fift/whitepaper#6-3-dictionary-manipulation) in the whitepaper for a list of words that create and manipulate TVM hashmaps. |

please switch localhost links to relative ones
and add link to /languages/fift/control#blocks

Links issue addresses in issue #1554. Crosslinks cannot be solved in this PR, since other PRs need to be merged first.
