The following unary operators are supported:
-(.user.birth.year - 1990)
The following binary operators are supported:
3 + 1 == 4 * 1
The following Python-style operators are also available as an alternative:
Ternary operator (conditional)
The ternary (conditional) operator is the only emuto operator that takes three operands. The ternary operator is the equivalent of the if statement in other languages.
"Foo" if 3 < 4 else "Bar" // "Foo"
3.14 if true == false else  // 
The spread operator
... allows an iterable (like an array or string) to be
expanded where zero or more elements are expected:
[1, 2, ...[3, 4], 5]
Takes an input and returns it unchanged.
Retrieves a certain property of the input.
.foo.bar is equivalent to
.foo | .bar
Property access can be made optional using a
The effect of this is that when the left hand side of
null, no error will be thrown. Instead,
null will be returned.
This code does not produce an error:
Retrieve a single element from an object or array, or retrieve a list of elements.
When the projection has a single element (e. g.
$["name"]) that property is
In any other case, a list of each requested element is returned.
Just like with property access, optional chaining can be used with projection
too. In this example, no error is produced. Instead, a
null is returned.
null ?[3, 4]
