Functions in JavaScript. 5B

Leonid Kovalchuk - March 1, 2023 Leave a Comment

A function in JavaScript is a reusable block of code that performs a specific task. All functions have a name, arguments, and a code block.

Calling a function executes the code contained within the function. This means the code inside the function will be run and any return values will be outputted when the function is finished running.

Passing a function argument refers to supplying a function with the data it needs to execute. This data is typically supplied in the form of values that are passed as parameters to the function. By passing arguments to a function, the function can be more versatile and dynamic as it can take different data values each time it is called.

The return keyword is used to return a value or data from a function. It can be used to explicitly return a value to the caller of the function, or to end the execution of the function and return control to the caller of the function. Additionally, it allows you to immediately terminate the function execution and provide a value or data to the caller.

Threat modeling is the process of defining and analyzing assets, identifying potential threats and assessing the likelihood that these threats could exploit those assets. It requires a comprehensive understanding of the system, its components, architecture, available security controls, and other security considerations. The goal of threat modeling is to identify and prioritize areas of risk that need to be addressed by security controls.

Regulations involved with data protection and cybersecurity:

The General Data Protection Regulation (GDPR)
The Data Protection Act
The California Consumer Privacy Act (CCPA)
Health Insurance Portability and Accountability Act (HIPAA)
Payment Card Industry Data Security Standard (PCI DSS)

Ransomware is a type of computer malware that restricts access to the victim’s data by encrypting it and demands a ransom payment in order to decrypt and regain access. Hospitals are often targeted because medical records and other personal data are highly valuable on the black market. Hospitals also have a greater incentive to pay the extortion fee since the alternative could potentially be a disruption of critical medical services.

Use strong passwords and two-factor authentication: Choose passwords that are at least 8 characters long and include a combination of numbers, symbols, and upper- and lower-case letters. Consider using two-factor authentication to add an extra layer of security to your accounts.
Keep your operating system and security software up to date: Regularly update your operating system and security software to protect against the latest threats.

Alan Turing was a British mathematician, computer scientist, and theoretical biologist. He is credited as being the father of modern computer science and artificial intelligence. The Turing Test is a test used to determine whether or not a computer is able to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. It was developed by Turing in 1950, and it works by having a human judge interact with two parties at the same time – one being a human and the other being a computer. The judge must determine which is which based solely on their conversation with the two.

A network effect is a phenomenon wherein the value or utility of an item increases as the number of its users grows. It is an example of positive feedback and a key factor of success for many products and services. Examples of network effects include networked telephones, social networks, and online marketplaces.

Pros:

Flexibility and scalability: Clouds can be easily scaled up or down based on the changing computing needs of businesses.
Cost Savings: Rather than investing in hardware and software, businesses can rent and pay for cloud computing services as they go.
Reliability: Cloud computing services are usually provided by a large number of geographically distributed data centers that offer high availability.
Security: Cloud computing providers offer enhanced security for their users’ data and applications, with regular data backups, anti-malware software, and encryption protocols.

SaaS (Software as a Service) is a way of delivering applications over the internet, usually on a subscription basis. This type of service eliminates the need for users to install and maintain application software and also provides access to applications over the internet.

PaaS (Platform as a Service) provides a platform as a service to software developers, allowing them to develop, run, and manage applications without the complexity of building and maintaining the infrastructure. This type of service provides developers with access to servers, storage, networking, and hosting technology.

IaaS (Infrastructure-as-a-Service) is a type of cloud computing that provides virtualized computing resources over the internet. With IaaS, businesses rent virtual server space, storage and networking capacity from a cloud service provider. The provider hosts and maintains the hardware, while businesses access the resources, they need using a web-based interface.

Product managers are responsible for the product development cycle from concept to completion.

Descriptive analytics is a type of analytics that uses historical data and summarizing it into meaningful patterns, such as the analysis of customers’ purchasing histories. Descriptive analytics provide the “what has happened” information.

Predictive analytics is a type of analytics that looks at historical data, identifies patterns and trends, and then uses them to predict future events and outcomes. Predictive analytics can help organizations make better decisions and anticipate needs and future demands.

Data is typically defined as information that is stored and organized in a structured manner that can be easily analyzed. Big data, on the other hand, is large, complex collections of data that typically contain many different types of data sources and formats. Big data can include a wide variety of data types such as images, audio, video, and text. Big data can also come from sources such as social media, mobile devices, financial transactions, and sensors. Big data can often contain more than Terabytes of data and must often be analyzed using different techniques such as machine learning.

Companies use big data to gain insights on customer behavior, market trends, and operational efficiency. By analyzing large sets of data, businesses can better understand their current market and customer needs, as well as anticipate future customer behavior. This can help companies make more informed decisions, predict future customer needs, and ultimately improve operational efficiency. This can be especially useful in industries such as e-commerce, where data-driven decisions can help a company reduce costs and boost profits.

Radio Frequency Identification (RFID) is a type of automated data capture technology that utilizes radio waves for communication between a tag consisting of an antenna, a transceiver and a processor, and a reader. The transponder embedded in the tag contains a unique identification code that is read by the reader, which in turn allows the reader to identify, locate and track objects in a supply chain. RFID tags can be affixed to goods, assets and personnel to ensure tracking, authentication, control and visibility throughout the supply chain.

An Entity Relationship Diagram (ERD) is a graphical representation of a database system that illustrates the relationships between entities or concepts within that system. It typically shows the components of the system and the relationships among different parts of the system, such as entities, attributes, relationships, and constraints. ERDs can be used to design a database or to analyze and improve an existing one.
The two notations for ERD’s are Chen’s notation and Crow’s Foot notation.
The primary symbols in literature refer to an object, image, word, or action that has its own meaning and can be used to represent an abstract idea. Examples of primary symbols include a rose for love, a dove for peace, a book for knowledge, and a cross for faith.
The different relationships in crow’s foot notation are one-to-one (1:1), one-to-many (1:N), and many-to-many (N:N).
The 1:1 relationship is indicated by a single line connecting two entities, while the 1:N relationship is indicated by a line connecting one entity to another with an arrowhead at the end of the line pointing to the entity on the other side. The N:N relationship is indicated by two lines with a crow’s foot at the junction of the two lines, indicating that many instances of one entity.
Salesforce is a cloud-based customer relationship management (CRM) platform developed by Salesforce. It provides businesses with a suite of applications designed to help them manage customer relationships, maintain and track customer data, and integrate with other business systems. It also provides tools to help with marketing automation, customer service, analytics, and application building.
1. One-one (1:1) cardinality: This type of cardinality is the most basic relationship, representing a single record in one table that corresponds to a single record in another table. This relationship is typically utilized to build associations between two tables by establishing a primary/foreign key relationship.

2. One-many (1:N) cardinality: This type of cardinality is used to create relationships between two tables, where one table has multiple related records in the second table. This relationship is typically used in more complicated database structures, and one table will contain a foreign key field which will link it
