What is DOM in JavaScript?

 What is DOM


DOM stands for Document Object Model. It is a programming interface for web documents that provides a way for web browsers and programming languages to interact with the content of a web page.

In simpler terms, DOM is a hierarchical structure that represents the elements of an HTML or XML document as objects. Each object in the DOM represents a different part of the document, such as a paragraph, image, link, or form. This allows developers to manipulate the content and structure of a web page dynamically using JavaScript, CSS, or other programming languages.

For example, using DOM, developers can add or remove elements from a web page, change the content of existing elements, or respond to user interactions like clicks or inputs. Overall, the DOM is a crucial part of web development, enabling the creation of interactive and dynamic web applications.

WHAT ARE NEURAL NETWORKS? | Comingfly

WHAT ARE NEURAL NETWORKS ? Neural Networks the process of machine learning are neural networks. These are brain-inspired networks of interconnected layers of algorithms, called neurons, that feed data into each other, and which can be trained to carry out specific tasks by modifying the importance attributed to input data as it passes between the layers. During training of these neural networks, the weights attached to different inputs will continue to be varied until the output from the neural network is very close to what is desired, at which point the network will have 'learned' how to carry out a particular task. A subset of machine learning is deep learning, where neural networks are expanded into sprawling networks with a huge number of layers that are trained using massive amounts of data. It is these deep neural networks that have fueled the current leap forward in the ability of computers to carry out task like speech recognition and computer vision. T here are vario...

What is Java? | Comingfly

What is Java? Developed by Sun Microsystems in the mid-1990s, Java was originally built to be a high-level and object-oriented programming language that looks and feels similar to C++. Along with being extremely popular, Java can implement a wide variety of algorithms, which are very useful to the machine learning community. Java is regarded as one of the most secure programming languages, largely due to its use of bytecode and sandboxes. Java manages to harness much of the power of C++ while overcoming its security issues and overall complexity. But with all of its improvements over C++, Java has a reputation for being slower than many other programming languages. Additionally, as of 2019, Java has implemented commercial licensing for certain business applications, which can be costly.
