Encapsulation
Encapsulation is the privatization of an object’s data while providing publicly available methods for users to operate on the private data.
Encode
Encode means converting a character from its standard form into code. By so doing, only those who understand the applied coding system will know the original character.
Encode (Computing)
Encode means converting human-readable characters, such as 6
, G
, and %
, into computer-readable characters (bits).
For instance, the bits (binary digits) form of the decimal number 7
is 111
. In other words, using 111
to represent 7
means you’ve encoded 7
into the computer-readable character of 111
.
Knowing how to encode is beneficial. And having some encoding converters can come in handy.
End Of (RegExp)
Regular expression’s end of operator ($
) asserts that you wish to find the RegExp pattern at the end of a string.
End-to-End Test (TDD)

Entry Point
An entry point is a file that a bundler uses to start building a dependency graph of all the project’s modules it needs to combine into a single browser-compatible module.
An entry point is the most critical file of a build step that links (directly or indirectly) to every other module in a project.
Enumerable Properties
An enumerable property is a property whose enumerable
attribute’s value is configured to be true
.
Equality Operator in JavaScript
The equality operator (==
) checks if its two operands are of equal value.
Error Handling Phase (ReactJS)

- During the component instance’s rendering
- In a lifecycle method of the component
- In any child component’s constructor
Error Handling Statement in JavaScript
An error handling statement is a piece of code that allows you to test, manage, and create custom error messages.
Escape (RegExp)
Regular expression’s escape operator (\
) specifies that you wish to escape a character’s default type.
exec()
in JavaScript
exec() executes a search for a regular expression pattern in its string argument.
Execution Time
Execution time (also called runtime) is the time during which a program is running.
In other words, execution time is the execution period (or lifecycle phase) of a program—which begins from the time the program is invoked and ends when the program’s invocation is closed.
Expensive Operation (Computing)
An expensive (or costly) operation is a resource-intensive task. It is an operation that uses a lot of resources, such as CPU, memory, or disk drive.
Expression Statement in JavaScript
An expression statement is any piece of code that expresses a value.
extends
Keyword in JavaScript
The extends
keyword in JavaScript makes one class the child of another constructor.
In other words, the extends
keyword assigns a constructor (class or function) as a specified class’s dunder proto.
