In programming, variables are used to assign a name to a piece of data and to use that name to reference the data elsewhere in the program.
myName = 'Zoe'
In programming, variables are declared by giving it a name and setting it to a value using an equals sign (‘=’). Variables can later be reassigned to other values.
dogBreed = 'corgi'
In programming, data types are how computers classify different forms of information. They include numeric, string and boolean types.
For example, if using number data type, the program will know that arithmetic can be performed on it, but it can’t be capitalized.
In programming, numbers are a common data type. They represent numerical values and can include numbers with and without decimal points.
In programming, strings are a common data type. They are any sequence of characters (letters, spaces, numbers, or symbols) surrounded by single or double quotes. Strings are commonly used to represent text, speech, symbols, and other non-numerical characters.
"Hello world""Great work!"
In programming, booleans are a common data type. They represent the logical ideas of
In programming, the logical AND operator (
&&) compares two values. It returns true when both values evaluate to true and false otherwise.
The following evaluates to true: grass is green AND fire is red 2 > 1 AND 6 > 5 3 == 3 AND 8 == 8
While this evaluates to false: trees are large AND ant are massive 5 < 4 AND 6 > 3 7 == 7 AND 0 == 9
