What does the second number after the colon in the trace line of the node.js stack mean?

Question

There are always two numbers in the node.js stack trace, line number then a: and another number. In the example below, in the first line there is faye-redis.js: 153: 36 and 153 - the line number in this file where the error occurs, but what does the number mean: 36?

node_modules/faye-redis/faye-redis.js:153:36 • publish.notify node_modules/faye-redis/faye-redis.js:72:16 • clientExists node_modules/redis/index.js:532:9 • try_callback node_modules/redis/index.js:614:13 • return_reply node_modules/redis/index.js:266:14 • RedisClient.init_parser events.js:96:17 • EventEmitter.emit node_modules/redis/lib/parser/hiredis.js:43:18 • execute node_modules/redis/index.js:488:27 • on_data node_modules/redis/index.js:82:14 • none events.js:96:17 • EventEmitter.emit net.js:397:14 • onread 

Answer 1

The first number is the row (row number), the second is the column (character in the row). In Javascript, many encoders usually install a lot of code on a single line using closures et al or use minifiers as a YUI compressor, so it often provides quite relevant information.
