Operators

Arithmetic, comparison, logical, and special operators.

Arithmetic

{a + b}     // Addition
{a - b}     // Subtraction
{a * b}     // Multiplication
{a / b}     // Division
{a % b}     // Modulo (remainder)

Comparison

{a == b}    // Equal
{a != b}    // Not equal
{a < b}     // Less than
{a <= b}    // Less than or equal
{a > b}     // Greater than
{a >= b}    // Greater than or equal

Logical

{a and b}   // Logical AND
{a or b}    // Logical OR
{!a}        // Logical NOT

Null Coalescing

Use ?? to provide a default value when an expression is null:

{nickname ?? name}
{user.phone ?? "Not provided"}

Pipe Operator

Use | to chain function calls, passing the left side as the first argument:

{items | $filter((x) => x.active)}
{items | $filter((x) => x.active) | $map((x) => x.name)}

Grouping

Use parentheses to control evaluation order:

{(a + b) * c}
{!(active and verified)}

Operator Precedence

From highest to lowest:

1. (): Grouping
2. . .?: Property access
3. !: Logical NOT
4. * / %: Multiplication, division, modulo
5. + -: Addition, subtraction
6. < <= > >=: Comparison
7. == !=: Equality
8. and: Logical AND
9. or: Logical OR
10. ??: Null coalescing
11. |: Pipe
