| 22 | * most node. The tail is the node that contains the offset directly.
|
| 23 | *
|
| 24 | * For example, the expression `a + b + c` might have an ast that looks

| 25 | * like:
|

| 27 | * / \
|
| 28 | * a +
|
| 29 | * / \
|
| 30 | * b c
|
| 31 | *
|
| 32 | * The path to the node at offset 9 would be `['+' at 1-10, '+' at 7-10,
|
| 33 | * 'c' at 9-10]` and the path the node at offset 1 would be
|
