JavaScript ; Naming conventions ; JavaScript naming conventions Variables. Names are case-sensitive, lowercase and uppercase are different. Start variable names with a letter, use camelCase for names. Variable names should be self-descriptive, describing the stored value. Boolean variables are usually prefixed with is or has. Functions The new Boolean() will return a Boolean object, whereas it returns a boolean without the new keyword. The boolean (lower case) is the primitive type, whereas Boolean (upper case) is an object in JavaScript. Use the typeof operator to check the types. Example: Boolean vs boolean. var b1 = new Boolean(true); For this, JavaScript has a Boolean data type. It can only take the values true or false. The Boolean() Function. You can use the Boolean() function to find out if an expression (or a variable) is true: Example. Boolean(10 > 9) JavaScript Boolean Reference. JavaScript Boolean is a datatype that returns either true or false In JavaScript, a boolean is used as a function to get the value of a variable, object, conditions, expressions, etc in terms of true or false. Syntax: Example: If the operands are equal, the equal to operator == returns true. Output: Here, the variables isTrue and isFalse are assigned the Boolean values true and false, respectively. COMPARISON OPERATORS AND BOOLEAN RESULTS: JavaScript provides several comparison operators that return Boolean values when used to compare two values. These operators include: Equality (==): Checks if two values are equal and returns true if There are two ways to create a boolean in JavaScript: by using the true and false literals or by using the Boolean () constructor. The true and false literals are used to create boolean values, while the Boolean () constructor can be used to convert a value of any other data type into a boolean.
