te.te.tmp(obj, callback)


If obj is potentially expensive code and you need to reference it multiple times (e.g. te`(${obj}.foo === 3 ? ${obj}.bar : ${obj}.baz)`) then you can use tmp to create a temporary variable that stores reference to it and return the result of calling callback passing this temporary reference. E.g. te.tmp(obj, tmp => te`(${tmp}.foo === 3 ? ${tmp}.bar : ${tmp}.baz)`) means that the potentially expensive expression in the original obj variable only need to be evaluated once, not 3 times.
