How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>
[example](https://example.com)
<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-js
selfandthatto refer tothis. I feel this way becausethisis an overloaded variable used in different contexts; whereasselfusually corresponds to the local instance andthatusually refers to another object. I know you did not set this rule, as I've seen it appear in a number of other places, but it is also why I've started to use_this, but am not sure how others feel, except for the non-uniform practice that has resulted.$(...).on('click', $.proxy(obj, 'function'))and$(...).off('click', obj.function).Function.prototype.call ()andFunction.prototype.apply (). Particularly withapply ()I've gotten a lot of mileage. I am less inclined to usebind ()perhaps only out of habit though I am aware ( but not certain ) that there may be slight overhead advantages to using bind over the other options.bind()will take a snapshot of the context where it's first encountered during interpretation... That is to say, when JavaScript gets to thebind()function for the first time, it will take the context forthisat that point! This can become tricky to troubleshoot, as the standard implementation ofbind()CANNOT be altered. Once a function has been bound to another object, it will remain bound to that object, and attempting to rebind it won't work.
