Data Types and Variables

+
    +
  1. Name JavaScript's three data types. Describe the types of data they store
    2. +
  2. JavaScript is a weakly-typed language. Describe what this means.
    3. +
  3. What are the naming rules for a variables name? What are naming conventions?
    4. +
  4. What is a constant in JavaScript? Describe how you would declare a JavaScript constant.
    5. +
+

Answers:

+
    +
  1. Number, String and Boolean
    2. +
  2. weakly-typed language implies that data types do not need to be defined at initialization, the compiler will decide, cast and convert the data type unless explicitly cast
    3. +
  3. A naming convention is a recommended way of naming variables to ensure readability and organize code. JavaScript uses camelCase for variables and classes and UPPER_SNAKE_CASE for constants
    4. + + let customerAge = 23;
    + const ONT_TAX_RATE = 0.13; +     +
  4. A constant is a variable whose value cannot be changed once initialized, making it constant. To define a constant, use the "const" keyword.

Operators

    +
  1. Explain the following binary operators: + - * / %
    2. +
  2. Explain the multiple uses of the + operator.
    3. +
  3. Describe how the increment/decrement operators (++ and --) work.
    4. +
+

Answers:

+
    +
  1. The + operator is used to get the sum, the - operator is to get the difference, the * operator multiplies, the / operator divides and the % (modulus) operator determines if two numbers divided have a remainder and how much of one
    2. +
  2. The + operator can be used to add two numbers together to find their sum, or you can use it to concatenate multiple Strings together.
    3. +
  3. The ++ (increment) operator is used to increase the value of a variable by exactly one. The -- (decrement) operator is used to decrease the value of a variable by exactly 1.
