 An effect only depends on the values that it read the last time it ran. This has interesting implications for effects that have conditional code.
 
-For instance, if `a` is `true` in the code snippet below, the code inside the `if` block will run and `b` will be evaluated. As such, changes to either `a` or `b` [will cause the effect to re-run](/playground/untitled#H4sIAAAAAAAAA31SXWvbQBD8K5slIBmErbiUgqoThPyD0Dzl-nAnreyjykro1q6D0H8Pp6taY9o-zuzM7cfchGzeCAt8YXHSUYMZtq4jj8XrhPI-hFogMFuVj8Ow9WfqJHDWePobX_csxOKxwNLXoxuk0qylIwEDCu69GKFUxhNtvq4F-69CbfhsfICspe7ZC5yGxgg9LQVQkApdZAOqgiloVtUyxUVA_XpieyB5ilya7JsktljUgdvWHZnxmWpJ8wzybHX9dI0cf6MjucNRbq1tz6FP8mk_XMDT6NrkVuG67lvoHFAGD3kGn_P4zBylrOWe2jb0T6-XuV42TcYTs-PDOvyicC2kZrPqbx22SDKw68Tz0jGgcvcnGi4bdwYv7x0pjW9mPDguYJ8PF8g1LuGV9iTSM_Rcd67-oaY4ZMjzzsyVAedhMnO5i7r_eULUd3au7OKx155y17hzFVcr48nBOm4KOTqvpsjMsGSiNH7Jc40QM1Ea9wFW5S7KKs2YYbg3FuFLzd_nD1eS-7_xAgAA).

 Conversely, if `a` is `false`, `b` will not be evaluated, and the effect will _only_ re-run when `a` changes.
