format

The format function takes a schema, data, and return format as input and returns a formatted version of the data that adheres to the specified schema and return format. The function is a part of the web3-utils library and is designed to be used with the Ethereum blockchain.

The schema parameter is a ValidationSchemaInput or Schema object that defines the structure of the data to be formatted.

The data parameter is the data to be formatted, which can be any type of data, including strings, integers, and objects.

The returnFormat parameter is a DataFormat value that specifies the format in which the data should be returned, such as JSON, YAML, or CSV.

The format function uses the schema to validate the data and ensure that it conforms to the specified structure. If the data does not validate, the function will throw an error. Otherwise, the function will format the data according to the specified return format and return it as a string.

Here's an example of how the format function can be used:

In this example, the format function takes in a schema, data, and return format, and returns a formatted version of the data as a JSON string. The schema defines the structure of the data, which must include a name property of type string and an age property of type integer. The data is validated against the schema, and if it validates, it is formatted as JSON and returned as a string.
