How to push an array into array

Question

data = [];
data.push({arrayName:x,secondArray: {name:x, value:y}});

Now how can you push an item into secondArray ? have tried with

data[0].secondArray.push({name:x, value:y});

But getting error like data[0].secondArray.push() is not a function.

{arrayName:x,secondArray: {name:x, value:y}} is object not array..Try data[0].secondArray={name:x, value:y}; or if you want secondArray to be an array then initialize it as an array. ata[0].secondArray.push({name:x, value:y}); will work in that case.. — Rayon

This is because secondArray is not a array but an object.

To add properties in an object you can use

secondArray.propertyName = Value;//not to use this syntax if 'propertyName' if not a valid string.

secondArray[propertyName] = Value;

For eg use : data[0].secondArray.name = 'x';

@RayonDabre Actually, it does answer the question as much as possible.

@ammoQ, if This is because secondArray is not a array but an object does answer this question according to you then no more arguments I feel question is unclear hence it is better to understand the question to provide better solution..

@RayonDabre The first revision of the answer didn't answer the question, you are right. When I came in, there already was the second revision with some code that IMO answers the question as good as possible.
