Exception — 9The representation of an unexpected situation that affects control flow.
Expression — 37An expression is a piece of source code that produces a value at runtime.
Field — 19A field is a variable that is a member of a class and may be part of an object.
Function — 10A function produces a return value from a list of argument values.
Garbage Collection — 0Garbage collection is the automatic deallocation of unreachable heap objects.
Implementation — 1
Inheritance — 16Inheritance is a way to define a class by reusing the definition of another class.
Input — 0The input of a program is information it reads from its environment.
Lifetime — 2The lifetime of a variable, array, or object is the duration from its allocation to its deallocation.
Literal — 17A value that is written itself in the source code.
Loop — 9A loop is a compound statement that repeats the statements in its body zero or more times.
Member — 7A member of a class can be a method or a field.
Method — 47A method is a function that is a member of a class and may operate on an object.
Mutability — 7Mutable means that a memory location can be reassigned new values.
Name — 6Names are used to denote constructs such as variables, classes, types, and members.
Null — 7The value null is a reference that does not refer to anything.
Number — 15A number is a value of a numerical type.
Object — 31An object is an instance of a class stored in a set of memory locations.
Operator — 21An operator is a symbol or keyword in source code that represents a built-in function.
Output — 3The output of a program is information it writes to its environment.
Parameter — 11A variable holding an argument received by a function.
Polymorphism — 1Polymorphism means that an expression can produce values of more than one type.
Precedence — 2Precedence determines how operators in expressions are grouped.
Primitive — 3A primitive value is of a scalar or built-in type and may completely fit into a single memory location.
Prototype — 1A prototype is an object that serves as an exemplar for new objects.
Recursion — 11A self-referential data structure or computation.
Reference — 26A reference value points to a sequence of memory locations that may contain an object or array.
Repetition — 3Repetition means multiple occurrences of the same data or multiple executions of the same statements.
Return — 10A return statement returns control from a function or method back to its caller.
Scope — 8The scope of a name is the region of source code in which the name can be used.
Self — 8Self is a reference to the object on which the current method operates.
Sequence — 2A sequence is an ordered collection of data or instructions.
Stack — 10A memory region containing the local variables and parameters of currently executing functions.
Statement — 3A command or instruction to be executed in an imperative program.
Static — 2A static aspect of a program does not depend on program execution.
String — 17A string is a sequence of characters.

Term — 0
Type — 36A type is a set of values supporting a certain set of operations.
Undefined — 3An undefined value represents the absence of a value.
Value — 19A value is data and may be the result of evaluating an expression or the contents of a variable.
Variable — 32A variable is a named location that holds a value.
