Syntax refers to the set of rules that defines the structure of statements in a programming language. It dictates how code must be written for the interpreter or compiler to understand and execute it correctly. Different programming languages have their own unique syntax, which can affect how easily a programmer can express their ideas.

For example, Python is known for its clean and straightforward syntax. It avoids unnecessary characters, such as semicolons, to indicate the end of a line; instead, a new line suffices. Additionally, Python uses indentation to define code blocks, which means that the placement of whitespace is crucial for the correct execution of the code ³.

In contrast, Julia offers a more flexible approach to syntax, allowing programmers to use various expressions and methodologies. This flexibility can lead to more creative and efficient coding practices, as it encourages programmers to explore different ways to solve problems ².
