nl_tokens: Checks if nodes are equal using the following by checking if they are both ignored have the same checksum or have the same contents .
pl_tokens: <mask> isEqualNode ( a , b ) { return ( // Check if both nodes are ignored. ( isIgnored ( a ) && isIgnored ( b ) ) || // Check if both nodes have the same checksum. ( getCheckSum ( a ) === getCheckSum ( b ) ) || // Fall back to native isEqualNode check. a . isEqualNode ( b ) ) }
