Form a collection of JavaScript arrays using a string that includes strings

Here is a string that needs to be converted into a JavaScript array:

['Value',2],['Value2',4],['Value3',10]

To convert this to a JavaScript array, the following code can be used:

var tmpStrings = "['Value',2],['Value2',4],['Value3',10]";     
var arrStrings = JSON.parse("[" + tmpStrings + "]");

However, there are unexpected character errors thrown when trying to parse the string. It was initially thought that single quotes might be causing the issue, but escaping them did not solve the problem. Interestingly, parsing integers seems to work fine as seen in the code below:

var tmpInts = "[4,2],[5,3],[6,3]"; 
var arrInts = JSON.parse("[" + tmpInts + "]"); 

Answer №1

To make sure JSON accepts the string properly, it's important to replace single quotes with double quotes.

console.log(JSON.parse("[" + tmpStrings.replace(/'/g, '"') + "]"));
# [ [ 'Value', 2 ], [ 'Value2', 4 ], [ 'Value3', 10 ] ]

In this code snippet, we are simply converting all occurrences of single quotes to double quotes in the string.

Note: Be cautious as this will change all single quotes to double quotes, even within the text.
