Expressions
Expressions are fundamental constructs in programming that evaluate to a value, combining variables, operators, and function calls. They form the building blocks of code for performing calculations, making decisions, and manipulating data. In most programming languages, expressions are used within statements to produce results or control program flow.
Developers should master expressions as they are essential for writing efficient and readable code in any programming task, from simple arithmetic to complex logic. Learning expressions is crucial for implementing algorithms, data transformations, and conditional operations, making them foundational for software development across domains like web development, data science, and system programming.
