Parameters
help
Event parameters list the data that an event contains.
| from |
address help
The type of this value is address, which means it stores an Ethereum address, such as a wallet address.
|
| value |
uint256 help
The type of this value is uint, which stands for unsigned integer. Integer means it's a whole number (such as 1, 12, 52) without fractions or decimals. Unsigned means it can't have a negative or positive sign, so it's always a positive number.

name
Variable
string
help
The type of this value is string, which is basically just plain text. It's called a string because it is a 'string' of letters.
symbol
Variable

uint8
help
The type of this value is uint, which stands for unsigned integer. Integer means it's a whole number (such as 1, 12, 52) without fractions or decimals. Unsigned means it can't have a negative or positive sign, so it's always a positive number.
totalSupply
Variable
uint256
help
The type of this value is uint, which stands for unsigned integer. Integer means it's a whole number (such as 1, 12, 52) without fractions or decimals. Unsigned means it can't have a negative or positive sign, so it's always a positive number.
balanceOf
Variable
mapping(address => uint256)
help
The type of this value is other.
allowance
Variable
mapping(address => mapping(address => uint256))
help
The type of this value is other.

Function parameters list what input the function expects from the user. Each
parameter must be given a value.

uint256 help
The type of this value is uint, which stands for unsigned integer. Integer means it's a whole number (such as 1, 12, 52) without fractions or decimals. Unsigned means it can't have a negative or positive sign, so it's always a positive number.

Properties
Visibility
help
Visibility determines if the function is visible to users and other contracts.
Only functions that are public can be used.
public
Mutability
help
Mutability tells you if a function can make changes on the blockchain.
View means the function can be called by anyone without
a wallet and without submitting a transaction.
transaction
Requirements
help
Requirements are checks that the function makes when it runs, and give you
insight on what conditions are required for the function to succeed.
Source Code
function transfer(address _to, uint256 _value) {
_transfer(msg.sender, _to, _value);
}
