Strings

None of the string methods modify this – they always return fresh strings.

charAt(pos: number): string ^ES1

Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

⚠️ UPDATE: I have moved the contents of this gist plus more to http://www.learnrxjs.io and https://github.com/btroncone/learn-rxjs. For expanded examples, explanations, and resources, please check out this new location!

A complete list of RxJS 5 operators with easy to understand explanations and runnable examples.

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Did you write tests? Are they mutually exclusive and collectively exhaustive? Do they pass?
Did you get a code review?
Have you verified that your code works, outside of tests?
Is your code DRY?
Did you follow the single responsibility principle at different levels of detail throughout all your functions, objects, files, folders, repositories, etc.?
Is your code readable? Can someone else tell you what it does?
Is your code self-documenting? Did you explain strange choices? Did you write documentation about how it works?
Do all your variables have self-explaining names?
Did you avoid writing overly long functions?
Do you document what your function inputs are? Are you explicit about what preconditions must be true about your function inputs? Are you explicit about what postconditions will hold about your function outputs, if the preconditions hold?
