The buffer object can be encoded and decoded into Base64 string. The buffer class can be used to encode a string into a series of bytes. The Buffer.from() method takes a string as an input and converts it into Base64.The converted bytes can be changed again into String. The toString() ... Read More

The util.format() method returns a formatted string that will use the first argument as a printf like format string. This format can also contain zero or more format specifiers. These specifiers can be replaced with the converted value from the corresponding argument.Following are some of the formatted specifiers:%s − String will ... Read More

The util.callbackify() method takes an async function as a parameter (or a function with Promise) and returns a function with the callback style. The callback will hold the rejection reason as the first parameter (or null in case of Promise) and the resolved value as the second parameter.Syntaxutil.callbackify(function)Parametersfunction − The input ...

The Hmac class is one of the many utility classes that is used for creating the cryptographic HMAC digests. The Hmac.digest() method is used for calculating all the data that is updated using the Hmac.update() method. If encoding is provided, a string will be returned, else a buffer is returned.Syntaxhmac.digest( ... Read More

The Hash class is one of the many utility classes that is used for creating the hash digests of data. The hash.copy() method creates a new Hash object that will contain a deep copy of the internal state of the current hash object.Syntaxhash.copy([options])Parametersoptions −This input parameter takes input to control ...

The util.inherits() method basically inherits the methods from one construct to another. This prototype will be set to a new object to that from the superConstructor.By doing this, we can mainly add some validations to the top of Object.setPrototypeOf(constructor.prototype, superConstructor.prototype).Syntaxutil.inherits(constructor, superConstructor)ParametersThe parameters are described below -constructor − This is a function ...
