The terms “strongly typed language “and “weakly typed language ” use to refer the evidence of different language patterns and design decisions.
Strongly Typed Language refers to a programming language that is an essential tool for building reliable and efficient software.
It improves code readability and maintainability and makes it easier for other developers to understand and modify the code.
Strongly typed language enforces strict type-checking, ensuring that all variables and expressions are correct before it used in the program.
It helps to prevent errors and improve the quality of the code.
One of the principal benefits of strongly typed language is that it provides the highest reliability and stability, reducing the risk of bugs and errors that can cause crashes or other issues. C#, Java, Scala, F+, Haskell, Python, and Groovy are some examples of strongly dynamic and static-typed languages.
On the other hand, Weakly Typed Languages frequently utilize in web development and scripting because of their usability and flexibility. Because data types do not need to be explicitly declared by the programmer, the code can be quicker and simpler to read. It is also simple for developers to use.
Weakly typed languages can be beneficial, but they can lead to errors and bugs which are difficult to detect and fix. the language does not require type verification in the compilation
Some prominent weakly typed language examples are Java-script, Perl, VB, PHP, C, C++, and shell.
Difference Between a Strongly Typed Language and a Weakly Typed Language
The key difference between a strongly typed language and a weakly typed language is in how the system handles data types. Strongly typed languages enforce strict type-checking during the compilation process,
while weakly typed languages allow more flexibility and only perform type-checking in runtime. This can affect the efficiency, memory usage, and error detection of the code written in these languages.
Here are some points we can highlight:
Data Type Enforcement
Under strongly typed languages, the enforcement of data types is strict. on the other hand, in weakly typed languages, there is more flexibility and implicit conversion between data types is allowed.
Dynamic Data Fix
Strongly typed languages fix the data types of variables, whereas, in languages with weak typing, the data type of a variable may dynamically alter depending on the usage situation.
Error Detection
In strongly typed languages, the compiler detects errors in the compilation when there is a mismatch between the data type of a variable and the operation performed on it. In weakly typed languages, errors detect in runtime when there is a mismatch between the data type of a variable and the operation performed on it.
Memory Usage
In strongly typed language memory is used more efficiently as the size of the data type is predetermined undoubtedly.
besides weak-typed language memory usage may be less efficient as the size of the data type is not predetermined, and the system may need to allocate more memory to accommodate different data types
Performance
In strongly typed language the code is more efficient as there is no need for run-time type checking.
since weak-typed language, the code may be less efficient as there is a need during run-time type checking.
Rigidity
Strongly typed languages can be more rigid and less forgiving, as they require strict adherence to data types
However, Strongly typed and weakly typed language has advantages and disadvantages, the choice of which type to use ultimately depends on the project’s needs and the developer’s preferences.
