`util.promisify()` in Node.js converts callback-based methods to promise-based, aiding in managing asynchronous code more cleanly. This alleviates callback nesting issues, enhancing code readability, and simplifying asynchronous operations through promise chaining....

The util.format() (Added in v0.5.3) method is an inbuilt application programming interface of the util module which is like printf format string and returns a formatted string using the first argument. The formatted string contains zero or more format specifiers in which the corresponding argument value is converted and replaced. It is used as a debugging tool in a synchronous method hence, it can have a significant performance overhead that could block the event loop. It is recommended not to use this function in a hot code path....

The “util” module provides ‘utility’ functions that are used for debugging purposes. For accessing those functions we need to call them by ‘require(‘util’)’....

The util.callbackify() method is an inbuilt application programming interface of the util module which is used to run an asynchronous function and get a callback in the node.js.Syntax:...

The util.deprecate() (Added in v0.8.0_ method is an inbuilt application programming interface of the util module which wraps fn (which may be a function or class) in such a way that it is marked as deprecated. When util.deprecate() method is called, it returns a function that emits a DeprecationWarning using the ‘warning’ event. The first time the returned function is called, the warning is emitted and printed to stderr. Once the warning is emitted, then the wrapped function is called. The warning is emitted only once if the same optional code is supplied in multiple calls to ‘util.deprecate()‘....

The util.types.isDate() method is an inbuilt application programming interface of the util module which is used to check the type for Date in the node.js....

The TextEncoder is an interface that takes a stream of code points as input and emits a stream of encoded UTF-8 codes. This is provided in NodeJS as an implementation of the WHATWG Encoding Standard ‘TextEncoder’ API. All instances of TextEncoder only support UTF-8 encoding....

The util.types.isSet() method of the util module is primarily designed to support the needs of Node.js own Internal APIs. It is used to check whether the passed instance in the method is a built-in Set instance or not....

The util.formatWithOptions() (Added in v10.0.0) method is an inbuilt application programming interface of the util module which is like printf format string and returns a formatted string using the first argument. It is somewhat identical to util.format() method, the exception in this method is that it takes an extra argument i.e. inspectOptions that specify options that are passed along to util.inspect() method. The formatted string contains zero or more format specifiers in which the corresponding argument value is converted and replaced. It is used as a debugging tool as a synchronous method....
