Boolean

In computer science, a boolean is a logical data type that can have only the values true or false. A boolean is how a programming language lets you represent true and false. Without the ability to represent boolean values a number of things in a language would no longer work. For example, in JavaScript, an if statement's conditional has to resolve to a boolean value for it to execute at all. Without the boolean conditional, a JavaScript for loop would never know when to stop looping.

***JavaScript if Statement***
if(boolean conditional) {
   //coding
}
if(true) {
  console.log("boolean conditional resolved to true");
} else {
    console.log("boolean conditional resolved to false");
  }
***JavaScript for Loop***
for(control variable; boolean conditional; counter) {
  //coding
}
for(var i=0; i<4; i++) {
  console.log("I print only when the boolean conditional is true");
}
