code: added Typescript and Javascript examples

[RiverTwilight]

Not sure whether these formats meet the requirement. If everything is okay I will continue to transcribe more:-)

If this PR is related to coding or code translation, please fill out the checklist.

• I've tested the code and ensured the outputs are the same as the outputs of reference codes.
• I've checked the codes (formatting, comments, indentation, file header, etc) carefully.
• The code does not rely on a particular environment or IDE and can be executed on a standard system (Win, macOS, Ubuntu).

Oh, I couldn't catch it anymore...as above mentioned I didn't change any text. You may need to check the raw file instead of the code diff.

Thank you @RiverTwilight for your clear code. It seems good and only has a small flaw.
And lack one part in the time_complexity.md:
=== "JavaScript"
js title="worst_best_time_complexity.js"
=== "TypeScript"
typescript title="worst_best_time_complexity.ts"
Please add it, thank you!

Thank you @RiverTwilight for your contribution!
The shuffle method has a little problem, which could not generate the true random data, you could check it in Will It Shuffle?

You could check one of the shuffle methods in wiki
Btw, I have updated the code, feel free to check it.
After updated, the random data are:

Thank you.
