Question 1

To catalyze

Answer 1

Cause or accelerate (a reaction) by acting as a catalyst

Question 2

Entropy

Answer 2

Lack of order or predictability, gradual decline into disorder

A thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system

Question 3

Monolithic

Answer 3

Formed of a single large block of stone

Question 4

LGTM

Answer 4

Looks Good To Me

Question 5

Inadvertent

Answer 5

Not resulting from or achieved through deliberate planning.

e.g many French leader cannot accept at all that American dominance is inadvertent

Question 6

Orthogonality

Answer 6

Statistically independent

Closely related to the DRY principle. If you combined the two, you’ll find that the systems you develop are more flexible, more understandable, and easier to debug, test and maintain.

Question 7

DOD

Answer 7

Definition Of Done

Question 8

Decoupled

Answer 8

separate, disengage, or dissociate (something) from something else.

Question 9

Singleton Pattern

Answer 9

In software engineering, the singleton pattern is a software design pattern that restricts the instantiation of a class to one “single” instance. This is useful when exactly one object is needed to coordinate actions across the system. The term comes from the mathematical concept of a singleton.

Critics consider the singleton to be an anti-pattern in that it is frequently used in scenarios where it is not beneficial, introduces unnecessary restrictions in situations where a sole instance of a class is not actually required, and introduces global state into an application.

Question 10

IIFE

Answer 10

Immediately Invoked Function Expression

(function() {
 var x = 20;
 var y = 20;
 var answer = x + y;
 console.log(answer);
 })();

Question 11

Immutable

Answer 11

Cannot be changed in the future

Question 12

To Abstract

Answer 12

Abstraction is one of the key concepts of object-oriented programming (OOP) languages. Its main goal is to handle complexity by hiding unnecessary details from the user.

That enables the user to implement more complex logic on top of the provided abstraction without understanding or even thinking about all the hidden complexity.

To detach something from

Question 13

KPI

Answer 13

Key Performance Indicator

Question 14

Inertia

Answer 14

is the resistance of any physical object to any change in its velocity.

Question 15

GUI Graphical User Interface

Answer 15

A visual way of interacting with a computer using items such as windows, icons, and menus, used by most modern operating systems.

Question 16

Type Coercion

Answer 16

Type coercion is the process of converting value from one type to another (such as string to number, object to boolean, and so on)

Any type, be it primitive or an object, is a valid subject for type coercion. To recall, primitives are: number, string, boolean, null, undefined + Symbol (added in ES6).

Type coercion can be explicit and implicit.

When a developer expresses the intention to convert between types by writing the appropriate code, like Number(value), it’s called explicit type coercion (or type casting).

Since JavaScript is a weakly-typed language, values can also be converted between different types automatically, and it is called implicit type coercion. It usually happens when you apply operators to values of different types, like
1 == null, 2/’5', null + new Date(), or it can be triggered by the surrounding context, like with if (value) {…}, where value is coerced to boolean.

The first rule to know is there are only three types of conversion in JavaScript:

to string
to boolean
to number

String(123) // explicit
123 + ‘’ // implicit

Question 17

Metadata

Answer 17

A set of data that describes and gives information about other data.

Question 18

Assertions

Answer 18

An assertion is a boolean expression at a specific point in a program which will be true unless there is a bug in the program. An assertion could simply be a comment used by the programmer to think about how the code works. Or an assertion could document a constraint on the system

Question 19

Assertive programming

Answer 19

Checking along the way.

Write code that actively verifies your assumptions
