Javascript functions and objects using equal operator -

Javascript functions and objects using equal operator -

i trying understand javascript concepts https://developer.mozilla.org/en-us/docs/javascript/a_re-introduction_to_javascript . please see code below;

function personfullname() { homecoming this.first + ' ' + this.last; } function personfullnamereversed() { homecoming this.last + ', ' + this.first; } function person(first, last) { this.first = first; this.last = last; this.fullname = personfullname; this.fullnamereversed = personfullnamereversed; }

i confused why function personfullname() called

this.fullname = personfullname;

why not called like;

this.fullname = personfullname();

and same below;

this.fullnamereversed = personfullnamereversed;

i know functions objects in javascript unable understand concept?

because person object assigning method, not results of function. reason doesn't phone call function.

this way can this.

var p = new person("matt", "m"); p.fullname(); // returns "matt m" p.fullnamereversed(); // returns "m, matt"

javascript function object equals operator-keyword
