Javascript string to special array

Question

I have a string:

var string = "test,test2";

That I turn into an array:

var array = string.split(",");

Then I wrap that array into a larger array:

var paragraphs = [array];

Which outputs:

[['test','test2']]

But I need it to output:

[['test'],['test2']]

Any clue how I can do this?

Iterate array and push them into paragraphs as .push([arrayItem]) — Sterling Archer

why... that doesn't make sense. Why would you have arrays that only have one index ever? wouldn't ['test','test2'] make more sense? — user400654

I would have done what @SterlingArcher had done here, but nem035's solution is more professional! — anugrah

Just map each item into an array containing that item:

var string = "test,test2";
var result = string.split(",").map(x => [x]);
                           // ^--------------
console.log(result);

let test_string = "test,test2";

let result = test_string.split(',').map(item => [item])

console.log(result)

You can get expected result using array Concatenation.

var string = "test,test2";
var array = string.split(",");
var finalArray=[[array[0]]].concat([[array[1]]])
console.log(JSON.stringify(finalArray));

What version of JavaScript are you targeting?

This might be a general answer:

var arr = "test,test2".split(",");
var i = arr.length;
while(i--)
    arr[i] = [arr[i]];
