What Goes into Code

Expressions

An expression is the smallest unit of code that produces a result. For example, 1+2 is an expression that gives an output of 3 when the program runs.

Print("{1 + 2}")

Print("{1 + 2}")

Copy full snippet(1 line long)

Print is a built-in function that tells the program to display whatever you put into the parentheses. In this case, "{1 + 2}" tells the program to calculate what 1 + 2 equals, and the sum will be printed when you open the log.

Values

A value is the information your program uses to operate. Examples of values are numbers or text.

Results

When an expression executes, then outputs a value, that value is a result.

Evaluation

To evaluate is to execute an expression in order to produce a value. Note that evaluate and value come from the same root word.

Operators

An operator is a symbol that represents an operation like addition (+), or greater than (>).
