Optionalauto_Let the solver record the constraints this one reads. Default: true
Optionalauto_Let the solver record when other constraints read this one. Default: true
Optionalcache_Keep track of the current value. Default: true
Optionalcheck_When invalidated, recompute right away and only invalidate dependents if the value actually
changed. Useful when many constraints depend on one that rarely changes. Default: false
OptionalcontextIf the value is a function, the this it's called with. Default: the global object
OptionalequalsHow to tell whether a new value is different from the old one. Default: ===
OptionalliteralIf the value is a function, treat the function itself as the value. Default: false
Optionalrun_Whether onChange computes the value right away (so that the next change is noticed). Default: true
Options that control how a constraint computes and tracks its value.
