A ValueFragment is created by this driver when a literal value or object is provided as an argument to the fql tagged template function.
ValueFragments must always be encoded with tags, regardless of the "x-format" request header sent.
const num = 17;
const query = fql`${num} + 3)`;
// produces
{ "fql": [{ "value": { "@int": "17" } }, " + 3"] }
A piece of an interpolated query that represents an actual value. Arguments are passed to fauna using ValueFragments so that query string injection is not possible.
