Original:
"[template1,template2]";

Parsing string as JSON with single quotes?
(10 answers)

I have a string containing an array, and want to extract the array and play with its objects.
var arrayString = "[{'name': 'Ruwaida Abdo'}, {'name': 'Najlaa Saadi'}]";
Basically, I am dealing with a JSON file in which some properties are in fact arrays but stored as strings. Hence, I need to deal with them as strings and convert them to array to use their objects.
What you have here is a JSON string. You can parse it to get the object / array:
var array = JSON.parse(arrayString)
Edit: I see your JSON string has single quotes. You need to replace all of them with double quotes before parsing:
JSON.parse(arrayString.replace(/'/g, '"'))

I need to convert list of strings
const ar: string[] = ['str1', 'str2']
to a string which contains ar container with square brackets [] and quotes "
const str: string = `["str1", "str2"]`
how to do it in proper way?
The format you want is a JSON array string. So use the JSON object's stringify function.
JSON.stringify(["some", "array", 123]);

Convert string with commas to array

var array = ["Charizard,Pikachu,Glalie,Delfox"];
I tried to use the split() method except that only affects string variables and not arrays.
My ultimate goal is to make array = ["Charizard","Pikachu","Glalie","Delfox"];
You can retrieve the value of the array an split it using as delimiter the comma ','
var array = ["Charizard,Pikachu,Glalie,Delfox"];
console.log(array[0].split(','))

I have this array
var p = [0,1,2,3,4];
and I want to convert each value in the array to string like
var p = ['0','1','2','3','4'];
any ideas, help please?
You can convert number to string simply by prepending empty string to it.
p = p.map(function(e){return ""+e});
All you need to do is pass the Number value to the String function to get a string out of a Number.
[0,1,2,3,4].map(function(value) { return String(value); });

how to convert the following string to map so that i can access the values
data.message ="{"id":"60653","key":"project1","self":"http://127.0.0.1:321/rest/api/2/issue/project1"}"
if your string is a valid JSON just use the JSON.parse function:
var str = '{"id":"60653","key":"project1","self":"http://127.0.0.1:321/rest/api/2/issue/project1"}'
var mydata = JSON.parse(str);
Use JSON.parse
