For example, when sending a file over a network, the file is read into a buffer and sent as a single chunk of data. 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. Īnd some other - substr() - which provide range of substring and 'length' can be positive only: string.substr(start,length)Īlso some maintainers suggest that last method string.substr(start,length) do not works or work with error for MSIE.In Node.js, the Buffer class is used to handle binary data. so: string.substring(from) positive or negative.

String.substring(from,to) as plus if 'to' index nulled returns the rest of string.

Need to say due to last discussion in comments, that jQuery is very much more often renewable extension of JS than his own parent most known ECMAScript. However, your method will works out of jQuery function, inside simple Javascript. In other words answer Erickson suggest really perfect solution. So, you can't use slice() inside jQuery because slice() is jQuery method for operations with DOM elements, not substrings. Sorry for my graphomany but post was tagged 'jquery' earlier.
