Get unique values from an array

var array = [1,2,3,4,1,2,1];

array.filter((x,i,a) => a.indexOf(x) == i);

// --result is as below

[1, 2, 3, 4];

filter method is explained as below
x--> the item in array
i--> the index of item
a--> the array itself

Looking for much shorter script? :-)

[... new Set(array)]

This gives the same result
[1, 2, 3, 4]

What is the difference between toString() and join() in JavaScript

There is a very subtle difference. Example codes below explain much better than lengthy paragraphs.

I am using Node command terminal to work on the example(cleared earlier commands using ctrl+l).

The example in the order of execution from the command prompt:
1. Assign an array of integers to a variable x.
2. Display the content of variable
3. Use of toString()
4. Use of toJoin() - we can see there is no difference in the result. However, join function can take parameter defining the type of delimiter. The default parameter is ",".
5-7. Use of different delimiters

Lazy to pick mouse to scrawl through site? - Go Vimium

Oh yeah... I am lazy to do things, things which are repetitive which can be either automated or have a better way of doing it. And I mostly get rid off using the mouse while programming but had no choice while browsing through a site. And then what - I searched for a workaround and came across this - Vimium. It's awesome! Try!

this command saves the output of the site page to the file named website in the current working directory

• -o (lowercase o) the result will be saved in the filename provided in the command line
• -O (uppercase O) the filename in the URL will be taken and it will be used as the filename to store the result
