• Statiscally typed JavaScript.

• Type checking is completed at compile time.
• Explicit type declarations are ususally required.
• Errors are detected earlier.
• Variable assignments are static and cannot be changed.
• Produces more optimized code.

Some common examples of programming languages that belong to this category are Java, Haskell, C, C++, C#, Scala, Kotlin, Fortran, Go, Pascal, and Swift.

• Dynamically typed JavaScript

• Type checking is completed during runtime.
• Explicit declarations are not required.
• Type errors are detected later during execution.
• Variable assignments are dynamic and can be altered.
• Produces less optimized code, runtime errors are possible.
