How to remove double quotes from array in JavaScript?

my data, this polygon coordinates google maps

["{lat:-8.089057558100306,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.1782636642456}", "{lat:-8.087867882261257,lng:112.17800617218018}", "{lat:-8.089057558100306,lng:112.15251445770264}"]

to

[{lat:-8.089057558100306,lng:112.15251445770264}, {lat:-8.100954123313068,lng:112.15251445770264}, {lat:-8.100954123313068,lng:112.1782636642456}, {lat:-8.087867882261257,lng:112.17800617218018}, {lat:-8.089057558100306,lng:112.15251445770264}]

after remove double quotes my data must be still array, not string.

Thanks

If you can't alter the results you get above, you have to work around it.

 var a = ["{lat:-8.089057558100306,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.1782636642456}", "{lat:-8.087867882261257,lng:112.17800617218018}", "{lat:-8.089057558100306,lng:112.15251445770264}"]; a = a.map(function(o){ var d = o.split(',').map(function(b){ return Number( b.replace(/(}|{lat:|lng:)/g, '') ); /* OR b.replace('{lat:', '') .replace('lng:', '') .replace('}', ''); */ }); return { lat: d[0], lng: d[1] }; }); console.log(a);

Iif you really trust that data, eval ing it is the simplest way to convert it:

 let data = ["{lat:-8.089057558100306,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.1782636642456}", "{lat:-8.087867882261257,lng:112.17800617218018}", "{lat:-8.089057558100306,lng:112.15251445770264}"]; console.log(data.map(s => eval('null,' + s)));

(The null, is just there to make eval treat this as an expression instead of a { block } .)

However, as always, eval can introduce code injection vulnerabilities if you're not sure about where the data comes from. And really, you should figure out how the data got this way in the first place and fix it up into a useful format there.

You can try regex

 var arr = ["{lat:-8.089057558100306,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.15251445770264}", "{lat:-8.100954123313068,lng:112.1782636642456}", "{lat:-8.087867882261257,lng:112.17800617218018}", "{lat:-8.089057558100306,lng:112.15251445770264}"] arr = arr.map(function(item) { var match = item.match(/lat:(\\-?[0-9\\.]+),lng:(\\-?[0-9\\.]+)/); return {lat: +match[1], lng: +match[2]}; }) console.log(arr)
