getFunctionSelector

getFunctionSelector is a function that takes a function definition or an AbiFunction object as input and returns the function selector, which is a unique 4-byte identifier that represents the function. The function selector can be used to identify the function in a smart contract and trigger the appropriate action.

The function can be used in various ways, including:

Passing a string representing the function name and its parameters, such as 'function ownerOf(uint256 tokenId)'
Passing an AbiFunction object that contains the function name, parameters, and other information.

The getFunctionSelector function is useful for developers who want to work with smart contract functions in a more convenient and efficient way. It eliminates the need to manually calculate the selector for a function, which can be a complex and error-prone process. Instead, developers can simply call the function and use the returned selector to identify the function in their smart contract.

const selector_2 = getFunctionSelector('ownerOf(uint256)')
// Output: 0x6352211e

// or from an AbiFunction on your contract ABI
const selector_3 = getFunctionSelector({...})
// Output: 0x6352211e
