language agnostic - 6 abstractions, 1 construct -

which prefer, , why:

typical

if (this.sun.hidden === true &&     this.moon.visible === false) {     print "its daytime" } 

possible unnecessary abstraction

if (issunhidden() === true &&     ismoonvisible() === false) {     print "its daytime" } 

removing syntax

if (issunhidden() &&     ismoonvisible()) {     print "its daytime" } 

i 1 readable, requires hard-coded "daytime" string

if (timeofday() === "daytime") {     print "its daytime" } 

this easy read

if (isitdaytime()) {     print "its daytime" } 

mixes printing time of day checking, not good

printdaytime(); 

anyway, personal preference large degree, there good, logical reasons prefer 1 on other , interested in hearing reasons - or possibly other variations of same construct if adds anything.

thanks!

of options, prefer:

if (isitdaytime()) {     print "its daytime" } 

this 1 not terrible:

if (timeofday() === "daytime") {     print "its daytime" } 

...though use enumeration or similar construct instead of literal string, like:

if (timeofday() === timeofday.day_time) {     print "its daytime" }
