Booleans and Equality

• A boolean variable can be either true or false .

• Example:

    const age = 18;
    const ofAge = age > 18;
    console.log(ofAge); // false

• Equal signs:

  • = sign: used for assignment/ updation of values

      let name = 'Soumya';
      name = 'Raja';

  • Out of == and ===, you should almost always use ===.

  • == and === are used for equality comparison.

      console.log(age === 18); // true

  • == vs === :

    === checks both type & value.

    == only checks value.

      10 === "10" // false as values are same but types are not
      10 == "10" // true as values are same
