In the age of connectivity, digital marketing has become the best way to attract customers and boost businesses. Traditionally, the cornerstone of an online strategy is websites, but developing them requires investment, time, and mainly technical knowledge from IT programmers.
To develop IT solutions, one must have mastery and know how to differentiate some fundamental elements that are part of the process. Some, like API, Library, and Framework, despite being distinct, are concepts that complement each other and can sometimes be confused; however, they are extremely important for building not only websites but also software, mobile applications, etc.
API
API, or Application Programming Interface, is software developed to provide an interface with established rules for integration between systems. It is the documentation that determines how a programmer can perform a task through a library and how their code interacts with it.
Library
A Library is a set of functions, typically organized into classes, that can be used for software development, simplifying the programming language. There are various classes of libraries, with different purposes, such as database access, image manipulation, among many others. They are the foundation for creating frameworks.
Frameworks
Frameworks are development platforms that provide a consistent standard support for building an application and that, through programming, allow customizing functionalities to make them specific according to the application. It can be built using various libraries and integrated with APIs to constitute an ideal structure for the intended development, and they are mainly used because they accelerate development.
In the market, there are several languages and frameworks, such as JavaScript, Java, HTML, CSS, PHP, Python, and Ruby.
