Subject: replace 'instanceof Buffer' with Buffer.isBuffer()
X-Git-Url: https://zoso.dev/?a=commitdiff_plain;h=08ef8b54e3b7c29a697a4a45269d0172179d136c;p=buffer.git

replace 'instanceof Buffer' with Buffer.isBuffer()

To support buffers that come from other contexts like iframes, or Buffers that come from multiple version of buffer embedded in the same browserify bundle

Always use Buffer.isBuffer!!!
