Buffers are useful in a variety of use cases, such as when working with binary data, sending data over a network, or reading and writing data to a file. Buffers can also be created using the Buffer.alloc() method, which allocates a new buffer of a specified size, or the Buffer.allocUnsafe() method, which allocates a new buffer of a specified size without initializing its contents. A buffer is created using the om() method, which takes a string or an array of integers as input and returns a buffer. Buffers are like arrays of integers, but they represent raw binary data instead of numeric values. It is a global class that provides methods to create, manipulate, and read binary data in the form of buffers. inde圎nd represents a character that's before indexStart), an empty string is returned.In Node.js, the Buffer class is used to handle binary data.

If inde圎nd <= indexStart after normalizing negative values (i.e.

More formally, in this case, the substring ends at max(inde圎nd + str.length, 0).

If inde圎nd < 0, the index is counted from the end of the string.

If indexStart = str.length, slice() extracts to the end of the string.

If indexStart >= str.length, an empty string is returned.For example, str.slice(1, 4) extracts the second character through the fourth character (characters indexed 1, 2, and 3). Slice() extracts up to but not including inde圎nd. Changes to the text in one string do not affect the other string. Slice() extracts the text from one string and returns a new string.
