For example, `1` pushes the number 1 onto the stack. - **Arrays**: You can push arrays onto the stack. For example, `[1 2 3 4]` pushes the array {1, 2, 3, 4} onto the stack. - **`.`**: The `.` operator pops the top element from the stack and discards it. +- **`:`**: The `:` operator duplicates the top element of the stack ## Array-first keywords - **`@`**: the `@` keyword allows you to grab a specific value from an array by index, e.g. `[10 20 30] 2 @` would return the value `20`. |
