## Ejemplo

|
|
|
```python
|
|
jaccard_similarity(["a", "b", "c"], ["b", "c", "d"])
|
|
# 0.5
|
|
|
|
jaccard_similarity(["a", "b"], ["a", "b"])
|
|
# 1.0
|
|
|
|
jaccard_similarity([], [])
|
|
# 0.0
|
|
```

## Notas
|
|
|
|
Convierte las listas a sets internamente. Retorna 0.0 si ambas listas son vacias. Util para comparar conjuntos de tokens, features de malware, IoCs compartidos entre muestras, o tags de vulnerabilidades.
