Can a dynamically-typed language be strongly typed?

Dynamically typed languages (where type checking happens at run time) can also be strongly typed. A weakly typed language has looser typing rules and may produce unpredictable or even erroneous results or may perform implicit type conversion at runtime.

Which is better statically typed or dynamically-typed?

Statically typed languages have better performance at run-time intrinsically due to not needing to check types dynamically while executing (it checks before running). Similarly, compiled languages are faster at run time as the code has already been translated instead of needing to “interpret”/translate it on the fly.

Are dynamically-typed languages faster?

Dynamically typed languages must make all of their checks at runtime because the type might change during the course of the execution. Static typed languages resolve all types during compile time so the cost is consumed up front, one time. This is the main reason why dynamic typed languages are typically slower.

Is Java a dynamically-typed language or a statically typed language?

Java is statically-typed, so it expects its variables to be declared before they can be assigned values. Groovy is dynamically-typed and determines its variables’ data types based on their values, so this line is not required.

What does it mean for a language to be strongly-typed statically typed what prevents say C from being strongly-typed?

A strongly-typed language has values that have a type at run time, and it’s difficult for the programmer to subvert the type system without a dynamic check. But it’s important to understand that a language can be Static/Strong, Static/Weak, Dynamic/Strong or Dynamic/Weak.

How does dynamically typed language differ from statically binding language?

Statically typed languages perform type checking at compile-time, while dynamically-typed languages perform type checking at run-time. Statically-typed languages require you to declare the data types of your variables before you use them, while dynamically-typed languages do not.

Why is JavaScript dynamically-typed?

JavaScript is called a dynamic language because it doesn’t just have a few dynamic aspects, pretty much everything is dynamic. All variables are dynamic (both in type and existance), and even the code is dynamic. You can create new variables at runtime, and the type of variables is determined at runtime.
