All JavaScript variables must be identified with unique names. These unique names are called identifiers.

Identifiers can be short names (like x and y) or more descriptive names (age, sum, totalVolume).

The general rules for constructing names for variables (unique identifiers) are:

  • Names can contain letters, digits, underscores, and dollar signs;
  • Names must begin with a letter;
  • Names can also begin with $ and _;
  • Names are case sensitive (y and Y are different variables);
  • Reserved words (like JavaScript keywords) cannot be used as names.

In JavaScript, the equal sign (=) is an “assignment” operator, not an “equal to” operator. This is different from algebra.
