for loops, which have a beginning and
end. Others, though, stand all on their own: one statement, one line.
Among these simple statements are those for assignment.
The Assignment Statement
The most common statement is the assignment statement. Itâs an expression consisting of a variable on the left side, an assignment operator (=), and whatever is being assigned on the right.
The expression on the right can be a literal value:
nValue = 35.00;
Or, a combination of variables and literals combined with any number of operators:
nValue = nValue + 35.00;
And it can be a function call:
nValue = someFunction(ââ);
More than one assignment can be included on a line. For instance, the following assigns the value of an empty string to multiple variables, on one line:
var firstName = lastName = middleName = "";
Following the assignment statement, the second most common type of statement is the arithmetic expression that involves the arithmetic operators, discussed next.
In the last section, the second example was a demonstration of a binary arithmetic expression: two operands are separated by an arithmetic operator, leading to a new result. When paired with an assignment, the result is then assigned to the variable on the left:
nValue = vValue + 35.00;
More complex examples can use any number of arithmetic operators, with any combination of literal values and variables:
nValue = nValue + 30.00 / 2 ...
