buffer.writeUInt32LE()

buf.writeUInt32LE(value, offset[, noAssert])

Writes value to the Buffer at the specified offset with specified endian format (writeUInt32BE() writes big endian, writeUInt32LE() writes little endian). The value should be a valid unsigned 32-bit integer. Behavior is not defined when value is anything other than an unsigned 32-bit integer.

Set noAssert to true to skip validation of value and offset. This means that value may be too large for the specific function and offset may be beyond the end of the Buffer leading to the values being silently dropped. This should not be used unless you are certain of correctness.

Example:

const buf = Buffer.allocUnsafe(4);
buf.writeUInt32BE(0xfeedface, 0);

console.log(buf);
  // Prints: <Buffer fe ed fa ce>

buf.writeUInt32LE(0xfeedface, 0);

console.log(buf);
  // Prints: <Buffer ce fa ed fe>
