AI Coding Assistants For Programmers


The modern industry heavily depends on the tempos of software development and its successful performance. Businesses address professional IT companies, like Atlasiko Inc., expecting to get their perfect solution as soon as possible. It puts a lot of pressure on programmers, so to facilitate their work and ensure great results they often use innovative technology of AI coding. The software development industry is one of the most significant beneficiaries of AI programming solutions. Coding assistant tools accelerate processes and help to save a lot of time and effort during code writing.

In this article, we’ll explore the use of AI for developers, the principle of work, and the main reasons why programmer tools on the artificial intelligence basis are so popular. We also analyzed the most efficient AI-powered coding tools, went through their features and characteristics to compile the list of the best tools for AI coding. Read ahead to find out more about artificial intelligence code generation and consider your options for programming with AI.

What is an AI-powered coding assistant?

AI coding assistant is a tool that utilizes machine learning technology and modules to help with coding by doing automatic code generation, spotting bugs, correcting mistakes, etc. To generate code lines, an AI tool, following its algorithms, accesses open-source projects to analyze existing code. Based on that analysis, the coding assistant suggests to the programmer use intelligent code completion. The auto code completion function means that such an AI-powered coding tool is able to offer and allows insert full blocks of code, parts of finished scripts, methods, classes, variables, etc. The automatic coder with AI reads your line of code and then compares it to the published codes from open-access libraries, public repositories, or the machine learning datasets the coding assistant used. After the evaluation of common patterns, it offers you the best options to add to the code. In the same way, the AI-powered tool is able to spot bugs in code and fix them, do refactoring, optimization, and code review with AI assistance.

Most AI tools also enable writing code based on ordinary language using the technology of natural language processing (NLP). It means that the AI coding assistants can understand regular English or other supported languages and basically turn them into code lines. To get this coding help, developers need to formulate a comprehensive command or thoroughly describe the function for the AI tool to understand. Then once again it’ll search for a code that meets the description.

Why developers need artificial intelligence coding

AI autocomplete solutions are considered to be such helpful tools for programmers for very practical reasons. AI-powered code generation tools assist code programmers in creating high-quality software faster with less mundane work. Let’s look closely at the main reasons why developers choose artificial intelligent coding assistants and how such an AI that writes code can benefit the software development process.

  • Automation
    As a rule, lots of manual processes negatively influence the work of software developers. Basically, all programs require writing the same code line again and again, thus it can be bothersome. An AI coding assistant is capable of auto generation of code, checking for errors, and optimization of code smells (parts of code that need some improvements to be more efficient). The automation of these usually tedious processes surely facilitates routine coding.
  • Acceleration
    Naturally, with such a level of automation in AI coding the overall software development speeds up. With AI wring code, developers don’t need to spend hours on time-consuming routine tasks and can pay attention to more important ones.
  • Optimization
    Codewriting AI is good for optimization purposes. An artificial intelligence coder is not just able to complete the line for you, but also to read the script and suggest the most suitable ways to optimize some parts.
  • Quality
    AI code generation, AI-powered capabilities to spot bugs in code, suggestions of improvement, and other features of AI tools for coding help positively impact the quality of developed software. Programmers use an AI-powered tool to spot code mistakes and inefficient parts that human eyes could’ve missed without the AI helper. As a result, they get a responsive IT solution.
