Uncaught TypeError: data.push is not a function

Question

I am trying to push

data.push({\"country\": \"IN\"});

as new id and value to a json string. but it gives the following error

Answer 1

Also make sure that the name of the variable is not some kind of a language keyword. For instance, the following produces the same type of error:

var history = [];
history.push("what a mess");

replacing it for:

var history123 = [];
history123.push("pray for a better language");

works as expected.
