Javascript, convert unicode string to Javascript escape?
(6 answers)
Closed 1 year ago.
Just from a browser developer console or Node.js repl, what's an easy way to transcribe a string as its unicode representation? For example I can input '\u0048\u0065\u006C\u006C\u006F' and the repl will show me 'Hello'
> '\u0048\u0065\u006C\u006C\u006F'
"Hello"
How can I reverse this?
> something('Hello')
"\u0048\u0065\u006C\u006C\u006F"
For example. I hope there are some convenient built-ins or browser console/repl support.

I have the following line of Javascript code:
shell.flash.success('Some string');
However in Chrome Developer Tools this is appearing as:
o.flash.success("Some string")
(nb. o instead of shell because it's minified)
I noticed the same thing in IE.
Why does it display the string with double quotes when single quotes were used?

I have this PHP regex:
/^[\p{L}\p{M}]+[\p{L}\p{M}\-\s]*$/u
and I want to convert it to jQuery. I tried multiple solutions that I found online, but nothing really worked. I tried using
new RegExp("/^[\p{L}\p{M}]+[\p{L}\p{M}\-\s]*$/u");
but that didn't help.
This is because \p{L} and \p{M} don't exist in the JavaScript RegEx engine. This answer provides solutions for matching Unicode categories: https://stackoverflow.com/a/26659285/1920035

I'm a bit of a beginner still and keep coming across this in code:
${Math.round(newProps.percent)}% surrounded by backticks
or
${currentBillingStartDate} surrounded by backticks and not using the percent.
I'd like to understand when it should be used and why.
The percent sign is just a character that is meant to be interpolated with the expression inside the ${variable}. The result would be a string that looks like "55%"

Can someone please explain to me what is a Line Terminator? I have trouble searching it online. It may be slightly irrelevant to the question but I would just like to know.
A line terminator is OS specific. This doesn't have anything to do with JavaScript. On windows a line is terminated by the control character sequence \r\n, On UNIX like systems, it is \n.
Recall that control characters aren't printable characters, so the \r and \n is conceptual, but usually they're put in string literals to represent the control character.
