(greater than and lower than) or equal strict forms

Question

greater than or equal than >= and lower than or equal than <= strict versions in JavaScript? Similar to === and !==.

example:

false >= 0
true
false >== 0
VM174:2 Uncaught SyntaxError: Unexpected token =(…)

For "Y you will ever need it?"

!undefined >= 0 // some bad code like this in 10000 rows for example
true

example of defined strict versions, greater or equal than strict and respectively the other way around can be defined too.

function gtEStrict(arg1,arg2){
  if ( typeof arg1 === typeof arg2 ) {
     if ( arg1 >= arg2 ) {
       return true;
     }
  }
  return false;
}

gtEStrict(0,0)
true
gtEStrict(!undefined,0)
false

only numbers can be compared this way so why do you need the non-existent strict equal? — nicholaswmin, Feb 02 '16 at 20:34
No, these operators don't exist. And why would you need them anyway? — Jon, Feb 02 '16 at 20:34
Are you trying to do that because `false` evaluates to `0` and `true` evaluates to `1`? — developius, Feb 02 '16 at 20:38
There's no feasible reason or way to determine if a value AND type is gt/lt another data type. You can compare the *string*'d types and it will compare ascii values (unicode?) but that's irrelevant — Sterling Archer, Feb 02 '16 at 20:39
no, but `<` and `>` only work on numbers and strings, so there's not as much ambiguity as there is with general equality comparison. — dandavis, Feb 02 '16 at 20:41
@vtz, btw, please tell me languages having gte/lte-strict comparsions. — ZhukovRA, Feb 02 '16 at 20:50

Long story short, no. These operators do not exist.

Ok, let's assume, that comparing operator a >== b exist. When it return false, what does it mean? a less than b or a does not strictly equals to b? You can read more in that anwser.

i will mark this an answer because of the link :) (good one). Obviously there is no standard operator for my question i was curious if someone faced this and waned to make quick dirty fix or checker ;) – Vitaliy Terziev Feb 02 '16 at 20:54
ah this will be confusing for beginners :) replacing with +1 and changing my answer to @molsons's – Vitaliy Terziev Feb 02 '16 at 20:57
