Could you please elaborate on what precisely qualifies something as being injective? Could you provide an example or two to illustrate the concept? Furthermore, how does the property of injectivity differ from other related mathematical properties like surjectivity or bijectivity? Also, in what contexts is the concept of injectivity particularly important or useful? Finally, are there any common misconceptions or pitfalls that beginners often encounter when trying to grasp the idea of injectivity?

Injective functions, also known as injection or one-one functions, exhibit a unique mapping property. This property ensures that each element in the codomain corresponds to only one element in the domain.

BTCC's spot trading service, for instance, ensures that each trade is unique and accurately reflected in the exchange's ledger. Futures contracts similarly rely on the injective principle to maintain the integrity of trading positions.
