Tips

There are lots of elements in Typst scripting that are not obvious, but important. All the book is designated to show them, but some of them

Equality

Equality doesn't mean objects are really the same, like in many other objects:

#let a = 7
#let b = 7.0
#(a == b)
#(type(a) == type(b))

That may be less obvious for dictionaries. In dictionaries the order may matter, so equality doesn't mean they behave exactly the same way:

#let a = (x: 1, y: 2)
#let b = (y: 2, x: 1)
#(a == b)
#(a.pairs() == b.pairs())

Use the keyword in, like in Python:

#let dict = (a: 1, b: 2)

#("a" in dict)
// gives the same as
#(dict.keys().contains("a"))

Note it works for lists too:

#("a" in ("b", "c", "a"))
#(("b", "c", "a").contains("a"))
