node.js 堆栈跟踪行中冒号后的第二个数字是什么意思?
在 node.js 堆栈跟踪中总是有两个数字，行号然后是 : 和另一个数字.在下面的示例中，第一行 faye-redis.js:153:36 和 153 是该文件中发生错误的行号，但是数字 :36 是什么意思?
In a node.js stack trace there are always two numbers, the line number then a : and another number. In the example below, the first line has faye-redis.js:153:36 and 153 is the line number in that file for where the error is occurring, but what does the number :36 mean?
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
推荐答案
第一个数字是行(行号)，第二个是列(行号).在 Javascript 中，许多编码人员习惯性地将大量代码用闭包等嵌套在一行中，或者使用像 YUI 压缩器这样的压缩器，因此它通常是相当相关的信息.
The first number is the row (line number), the second is the column (character on line). In Javascript many coders habitually nest a lot of code on a single line with closures et al, or use minifiers like YUI compressor, so it's often rather relevant information.
