Transforming this JSON via underscore or a javascript utility library? -

i have json looks so:

[{"target": "mydata.12.2", "datapoints": [[763.7, 1368821100], [762.1, 1368821160], [223.11, 1368821220], [886.54, 1368821280], [112.3, 1368821340]]}] 

i'd remove first key , surrounding array brackets reads:

{"datapoints": [[763.7, 1368821100], [762.1, 1368821160], [223.11, 1368821220], [886.54, 1368821280], [112.3, 1368821340]]} 

my javascript parsing skills leave bit desired , hoping help. perhaps underscore.js has assist here?

no need library. supposing first array called obj1, have do

var obj2 = obj1[0]; delete obj2['target']; 

note seem have no json here, plain javascript objects.

supposing want start json , json @ end, parse stringify :

var obj2 = json.parse(json1); delete obj2['target']; var json2 = json.stringify(obj2);
