Numbers represent numeric values, such as integers and decimals.
Strings are used to represent sequences of characters, enclosed in quotes.
Booleans are either true or false, which are essential for making logical decisions in our code.
Null represents the intentional absence of any object value, while undefined is used for variables that have been declared but not assigned a value..
Now that we understand data types, let's talk about operators. Operators allow us to perform various operations on our data. We have arithmetic operators, such as addition, subtraction, multiplication, division, and modulo. These are used for mathematical calculations.
Next, we have assignment operators. They are used to assign values to variables or update existing values. Comparison operators help us compare values and return a boolean result. Logical operators allow us to combine multiple conditions and perform logical operations.
We also have unary operators, which operate on a single operand. They include increment and decrement operators. Lastly, the ternary operator provides a concise way to write conditional statements.
