Word scramble
Unscramble the letters and write each key term on the line.
1
WNE ETP()
Each ______ makes a separate object from the same class. Every object has its own property values, but all of them share the same methods. Changing one object does not change the others.
2
OMHE.TNSIAEMDTH()
Inside a class, a method calls another method of the same object by writing this. before its name, such as this.isPassing(). Forgetting this. causes a ReferenceError.
3
IPOPESTRER DAN HSDETMO
Read the scenario: nouns (data to store) become properties and verbs (actions) become methods. Keep only the details the program needs and leave the rest out.
4
IOSR.CETSH = OECRS;
Modifying a class: add or change a constructor parameter, property or method, then update every new call that creates its objects and re-run your tests.
5
ENW NMA(PTEE, EAG)
Common class bugs: forgetting new, leaving out this. in the constructor, swapping the arguments, or misspelling a property so it reads undefined.
6
AMUDRLO ARGPRMO
A program built from small parts: a class for the data, an array of its objects, and helper functions that each do one job (like totals or searches), all run by a main function.
7
ALVINDDIUI PICATM
The harm a cyber attack causes a person, such as stolen money, identity theft, a locked-out account, lost private photos or messages, reputation damage and emotional distress.
8
ATIOAANORSNGLI APMTIC
The harm a cyber attack does to a business or group, such as downtime, recovery costs, lost customer trust, a damaged reputation and fines for breaking privacy laws.
9
ERXNEPTGTI
Inventing a believable story or fake identity, like IT support or a delivery driver, to build trust and talk someone into handing over information or access.

1WNE ETP() → new Pet() — Each new Pet() makes a separate object from the same class. Every object has its own property values, but all of them share the same methods. Changing one object does not change the others.
2OMHE.TNSIAEMDTH() → this.methodName() — Inside a class, a method calls another method of the same object by writing this. before its name, such as this.isPassing(). Forgetting this. causes a ReferenceError.
3IPOPESTRER DAN HSDETMO → properties and methods — Read the scenario: nouns (data to store) become properties and verbs (actions) become methods. Keep only the details the program needs and leave the rest out.
4IOSR.CETSH = OECRS; → this.score = score; — Modifying a class: add or change a constructor parameter, property or method, then update every new call that creates its objects and re-run your tests.
5ENW NMA(PTEE, EAG) → new Pet(name, age) — Common class bugs: forgetting new, leaving out this. in the constructor, swapping the arguments, or misspelling a property so it reads undefined.
6AMUDRLO ARGPRMO → modular program — A program built from small parts: a class for the data, an array of its objects, and helper functions that each do one job (like totals or searches), all run by a main function.
