There are no variables in Clio, instead we have constants. There are two ways to declare them:

In the above piece of code we put "Hello" in hello, and assign "world" to world . You can probably guess what the last line does. Constants translate to JavaScript const and they cannot be reassigned.

The => syntax for defining a constant is very useful if used in a chain or a flow, a concept you will learn about soon in the next few chapters.
