Boolean 1/4
What are Booleans Values
The boolean data type is either true or false. In programming, we often need to know if an expression (code snippet which evaluates to some value) is true or false so in that case, we use boolean values. In JavaScript, boolean variables are defined by the true and false keywords.
let isClear = true; console.log(isClear);
