If value is not a plain array, such code will work fine:
var value = { "aaa": "111", "bbb": "222", "ccc": "333" };
var blkstr = [];
$.each(value, function(idx2,val2) {
var str = idx2 + ":" + val2;
blkstr.push(str);
});
console.log(blkstr.join(", "));<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>(output will appear in the dev console)
As Felix mentioned, each() is just iterating the array, nothing more.

September 22, 2023[Javascript] Adding a string to an array?
I'm no JavaScript expert, but it seems to me that if you use += on an array, you end up with a string: From my browsers dev tools console: Imgur I'm not sure of the underlying mechanism here (hopefully someone will be along to educate me ...) but it seems obvious from this that you can't use += to add to an array, which is why your code doesn't work. Use push instead. Even in C# you can't use += to add to an array, so I don't know why you think it might work in JavaScript. EDIT: and in your code, word should be a string, not an array, surely, and so you can use += to ad each letter to the end of word. It's only words that needs to be an array and to use push.

r/JavaScriptTips on Reddit: How do I convert an array to a string with commas in JavaScript
April 13, 2023 -
In JavaScript, you can convert an array to a string with commas using the join()
method.
The join() method returns a string that concatenates all the elements of an array, separated by the specified separator, which in this case is a comma.
Here is an example:
const array = ['apple', 'banana', 'orange'];
const string = array.join(', ');
console.log(string);
// output: "apple, banana, orange"
In this example, we first define an array of three fruits. Then we use the join()
method with a comma and a space as the separator to create a string that lists all the fruits with a comma and a space between each one.
You can replace the comma and space separator with any other separator you like, such as a hyphen, a semicolon, or a newline character.
It's important to note that the join() method only works on arrays, and it will throw an error if you try to use it on any other type of object.

Use .join() ['a', 'b', 'c'].join(); // 'a,b,c' (defaults to ',' separator) ['a', 'b', 'c'].join(''); // 'abc' ['a', 'b', 'c'].join('-'); // 'a-b-c' // 4.

May 23, 2022 - We check to see if the element is equal to 'b'. If it is, we append that element with a separator. Otherwise we append the element without the separator. You can also use the array.reduce() method for joining with custom logic. The previous example with a for loop can be rewritten like this: const myArray = ['a', 'b', 'c', 'c', 'b', 'a', 'd']const myString = myArray.reduce((stringAccumulator, currentElement) => { const separator = ';' if (currentElement === 'b') { return stringAccumulator += (currentElement + separator) } return stringAccumulator += currentElement }, '')console.log(myString) // 'ab;ccb;ad'
