Struggling with a challenging coding problem, I am completely stumped on how to make it work.
function(obj) {
if ( (obj < 10) && (obj > 10) ) {
return true;
}
}
I've attempted various solutions such as manipulating the variable at an extremely short interval or creating a function for obj that updates a global variable each time it's called. Despite these efforts, nothing seems to be working. Any suggestions or hints on what obvious detail I might be overlooking?
The key lies in the variable name "obj". When comparing objects, the valueOf() method is utilized. By implementing a valueOf method that generates a different value each time:
function test(obj) {
if ( (obj < 10) && (obj > 10) ) {
return true;
}
}
var Obj = function() {
var flag = false;
this.valueOf = function() {
if( flag ) {
return 11;
}
flag = true;
return 9;
}
}
console.log( test( new Obj() ) );
The toValue of the object above initially returns 9 (9 < 10), then switches to 11 in subsequent calls (11 > 10).
