/**
 * Infer a smart contract method parameter type and then encode this parameter.
 * @param params - The parameters to encode.
 * @returns - The ABI encoded parameters
 *
 * @remarks
 * This method is useful when you don't know the type of the parameters you want to encode. It will infer the type of the parameters and then encode them.
 * However, it is not recommended to use this method when you know the type of the parameters you want to encode. In this case, use the {@link encodeParameters} method instead.
 * The type inference is not perfect and can lead to unexpected results. Especially when you want to encode an array, uint that is not uint256 or bytes....
 * @example
 * ```ts
 * const res = web3.eth.abi.encodeParameters(
 *    ["2345675643", "Hello!%"]
 *  );
 *
 *  console.log(res);
