I have an object as follows:

const params1 = { FunctionName: "Foo", Environment: { Variables: { test: "test" } } }

And I have another object as follows:

const params2 = { FunctionName: "Bar", Something: "Something", SomethingMore: "SomethingMore", Environment: { Variables: { sample1: "sample1", sample2: "sample2" } } }

I just want to append all the environment variables from params2 to param1, so params1 should finally be something like this:

{ FunctionName: "Foo", Environment: { Variables: { test: "test", sample1: "sample1", sample2: "sample2" } } }

How can I achieve the same, I am able to do this using the following code,

params.Environment.Variables = { ...params.Environment.Variables, ...oldVars.Environment.Variables }

But I have a restriction that I cannot use the spread operator, please help!

You can do this using object.assign

const params1 = { FunctionName: "Foo", Environment: { Variables: { test: "test" } } } const params2 = { FunctionName: "Bar", Something: "Something", SomethingMore: "SomethingMore", Environment: { Variables: { sample1: "sample1", sample2: "sample2" } } } Object.assign(params1.Environment.Variables,params2.Environment.Variables) console.log(params1)

You can use a for in loop.

const params1 = { FunctionName: "Foo", Environment: { Variables: { test: "test" } } } const params2 = { FunctionName: "Bar", Something: "Something", SomethingMore: "SomethingMore", Environment: { Variables: { sample1: "sample1", sample2: "sample2" } } } for (const key in params2.Environment.Variables) { params1.Environment.Variables[key]=params2.Environment.Variables[key]; } console.log(params1)
