There is no block-level scope in the javascript, and instead of JavaScript using function scopes, use the example below to learn how to use JS scopes In some programming languages like C, each piece of code within the curly braces has its own scope, and the variables are invisible beyond the declaration of their code snippet, which we call block-level scopes,

to a uint8 integer. Similarly, Uint16array, which treats bytes in Arraybuffer as a 16-bit unsigned integer, corresponds to one uint16 integer per two bits.And DataView is a view provided by the JavaScript API, which treats the data in Arraybuffer as a network stream, using a big-endian encoding that can be used to read or write data. Here we use it to read the value of a Uint32.Next is the Send method, the code is as follows:function Dosend(bytes){
