I need to modify a string in JavaScript as required.suppose
I have a string 4x i need to insert * between 4 and x and
get it as 4*x
if it is 9x i should get it as 9*x etc
if it is sin(4x) i should get it as sin(4*x)
if it is sin(x) i should get it as sin(x).
if it is sin(4 x+5) i should get it as sin(4*x+5)
how to do this in java script.
any help is appreciable.
Use replace() with capturing group
document.write('4x , 5x , 5x+3 , sin(4 x+5) , sin(4x)'.replace(/(\d+)\s*([a-z])/ig,'$1*$2'));

return hex(id(self.table[hash]))
I do not know how to convert the following code from python to java script.
You don't.
There is no equivalent code to that in JavaScript, since id returns the address of the object (in CPython anyway), and there's no way to do that in JavaScript.

I have no idea how to render the time of a post being posted on my blog. I am using express as backend and template engine (express-edge).
you could use https://www.npmjs.com/package/i18n-js if you need to translate a date into anothers langages
you could also just use this

I have a simple Regex to match 'der' - /der/g
I need the context around the match. Is there any way to build the regex that way? Thank you in advance.
If you want to match the context plus the search string, simply add the optional range before and after the searched string: .{0,5}der.{0,5}
If you want to get the context only, you have to fetch it separately: (.{0,5})der(.{0,5})
