1// To convert a boolean to a string we use the .toString() method
2let isValid = true;
3
4console.log(isValid.toString()); // outputs "true"
5console.log(isValid); // outputs true
6

1var myBool = Boolean("false");  // == true
2
3var myBool = !!"false";  // == true

1let toBool = string => string === 'true' ? true : false;
2// Not everyone gets ES6 so here for the beginners
3function toBool(string){
4	if(string === 'true'){
5      return true;
6    } else {
7      return false;
8    }
9}

1// Do
2var isTrueSet = (myValue == 'true');
3// Or
4var isTrueSet = (myValue === 'true');

1// Everyone does one extra check. Here is a better answer
2
3let toBool = string => string === 'true'; // ? true : false;
4// Not everyone gets ES6 so here for the beginners
5function toBool(string){
6	return string === 'true';
7}

1booleanToString = b => { return b.toString(); }
2// Way cleaner Version! easy readability!!
