Lists

[mlajtos]

Lists – ordered collection of any type

Lists will be implemented as arrays in JS. However, immutable.

Notation

• [expr, expr]
  • no, because tensors are more important right now
• (expr, expr)
  • weird, but nice
  • can be confusing
  • () will clash with None (doesn't have to)
    • can be empty list, but then these function calls can't be equivalent: fn!, fn()
      • there are functions that can take empty list as a "valid data": (Length () = 0) = (Length ! = !), (1,2,3) -> Map (v => v + 1), () -> Map fn, error: ! -> Map fn
  • (expr,) is single-element list
  • Python comma operator creates tuples
  • JS comma operator is a bad part, so can be altered
