Node.js Buffer.readUInt32LE Lab
In this lab, you will learn how to use Buffer.readUInt32LE(offset)
method in Node.js. The Buffer.readUInt32LE(offset)
method reads an unsigned, 32-bit integer from a buffer at the specified offset, in little-endian format.
The syntax for Buffer.readUInt32LE(offset)
method is as follows:
buf.readUInt32LE(offset[, noAssert])
where offset
refers to the starting byte-index for reading the 32-bit integer from the buffer, and noAssert
is an optional parameter. If noAssert
is set to true, it will allow reading outside of the buffer's bounds without throwing an error.
In this lab, you will create a utility function parseBuffer
that takes a buffer and an offset as input, and parses the unsigned, 32-bit integer from the buffer using the Buffer.readUInt32LE()
method.
You are required to export the parseBuffer
function and run several tests based on the challenges mentioned below.
