toHex

The toHex function is a utility method provided by the web3.utils module that converts any given value into its hexadecimal representation.

The toHex function takes a single value argument, which can be a string, number, bigint, boolean, object, or Uint8Array.

The function returns a string representing the hexadecimal representation of the input value. If the returnType parameter is set to true, the function will return the type of the value in addition to the hexadecimal representation.

Here are some examples of how the toHex function can be used:

In the first example, the toHex function is called with the number 10, and it returns the hexadecimal representation of 10, which is 0xa. In the second example, the toHex function is called with the string '0x123', and it returns the hexadecimal representation of the string, which is 0x123. Additionally, the returnType parameter is set to true, so the function also returns the type of the value, which is 'bytes'.
