Syntax

a = 10
a += 10
a -= 10
a *= 10
a /= 10
a++
a--

b = 10.5
c = [1, 2, 3]
d = [c, c, c]
e = {"myKey": a, "myOtherKey": c, "myOtherOtherKey": d}
e.myOtherOtherKey[0][2] // this is c[2] which is 3

// To run commands just type them:
say hi

// Multi line commands are available, you can break the new line character with backslash:
execute       \
  as @a       \
  at @s       \
  run say hi

// If you want to define a variable with no initial value you just do this:
define int my_var

a += c[2] - (d[0][1] * 10) / (d[1][2] + 7) // Supports mathematical expressions

// You can break lines in expressions too!
val = 10 + \
 5 - 4 * \
 a + 5

fl = 10.5
fl += 5.23
