values function in Node.js Buffer ModuleThe values function is a member function of Buffer class in the Node.js Buffer Module. The values function is called on an instance of Buffer and returns an Iterator for the bytes in the instance. The syntax of the values function is as follows:
buf.values()
values takes no parameters.
Iterator for values of buf.The values function creates and returns an Iterator for the values of the buffer buf.
values functionThe following code snippet provides an example of how to use the values function:
const b = Buffer.from('ABCXYZ');for (const v of b.values()) {console.log(v);}
In the above example, b is a Buffer instance of length 6 that contains utf-8 encoded bytes for the string ABCXYZ. The b.values() function returns an Iterator, which is stored in v. In every iteration of the for loop, the value of v is printed, which is basically an integer value for a byte of buffer b.
Note: In a
for...ofconstruct,b.values()is unnecessary asbitself would also return a valueIteratorin this case.
