The size function in the viem library returns the size of a hex or byte array value, measured in bytes. The function takes a single argument, value, which can be either a hex string or a byte array.
The size function is useful for quickly determining the size of a value, without having to manually calculate the number of bytes it occupies. This can be particularly useful when working with binary data, where the size of the data can be important for memory management or network transmission purposes.
Here are some examples of using the size function:
The size function returns a number value, representing the size of the input value in bytes.
