Expert writing Tips
Best practice
When discussing data types, specify the type directly, e.g., "the variable could be a string" or "the input could be string data".
Common error
Avoid using "of" to describe the data type. "Of" generally indicates possession or origin, not the type of data. Instead, use "a string" or "string data" to correctly express the variable's type.
