How change String to boolean?

Question

I wanna pass something logical and return it.

"1 > 2" //return false
"true" // return false
"0" // return false
"1" // return true.

Reason: I was kiddimg today try some comparisom, so I was doing:

console.log("Test: " + "1 > 2" + ((1>2)?true:false));
But all time writing the string I'm testing and again on (condition), I want just improve:

var varTest = " 1 > 2";
console.log("test: " + varTest + ((toBool(varTest)?true:false)).

(Because I'm using function, and typing two parameter one as String and other as boolean, I want pass one parameter and convert it.

Answer 1

start with this code:
function myfunc(input){
if (input == "false"){
return false
}
if (input == "true"){
return false
}
}

Answer 2

The only way to do that is to evaluate the string as code.
A way to do that is using eval or Function constructor:
