Initializing JSON object in TypeScript

json, typescript

Solution

I've eventually figured it out. All I had to do was to create data to "any" variable like this:

output: JSON;
obj: any = 
{
"col1":{"Attribute1": "value1", "Attribute2": "value2", "Attribute3": "value3"},
"col2":{"Attribute1": "value4", "Attribute2": "value5", "Attribute3": "value6"}, 
"col3":{"Attribute1": "value7", "Attribute2": "value8", "Attribute3": "value9"} 
};

and then cast it to JSON object:

this.output = <JSON>this.obj;

Problem

I'm new to TypeScript and I'm stuck at working with JSON. I need to create a simple JSON object and I keep on failing doing so. Here are my first attempts: ``` output: JSON; //declaration this.output = { "col1":{"Attribute1": "value1", "Attribute2": "value2", "Attribute3": "value3"}, "col2":{"Attribute1": "value4", "Attribute2": "value5", "Attribute3": "value6"}, "col3":{"Attribute1": "value7", "Attribute2": "value8", "Attribute3": "value9"} } ``` This doesn't work. I guess I should work with JSON.stringify function. Here's my attempt: ``` obj: any; //new object declaration this.obj = { "col1":{"Attribute1": "value1", "Attribute2": "value2", "Attribute3": "value3"}, "col2":{"Attribute1": "value4", "Attribute2": "value5", "Attribute3": "value6"}, "col3":{"Attribute1": "value7", "Attribute2": "value8", "Attribute3": "value9"} } this.output.stringify(this.obj); ``` But this still invokes TypeError. So to summarize my question: how to properly create and initialize JSON object in TypeScript?
