I'm trying to push an Object to an Array using the following command:

a = a.concat(b);

a = [];
b = {a: Object1, b: Object2 ....};

So I wan to have array a to be like a = [Object1, Object2...]

But the above statement results in:

a = [[Object1, Object2...][Object11, Object12...]];

How can I achieve this in JS?

If I ́m understanding what you want, you want just objects, not the keys. So, could be:

for( var key in b ){
 var value = b[key];
 a.push(value);
}
console.log(JSON.stringify(a));

Hope it helps...

You are concatenating two arrays with Array.concat() you need to use Array.push().

var a = [ObjectA];
var b = ObjectB;
a.push(b);
// a = [ObjectA, ObjectB];

var b = {ObjectA, ObjectB}
That makes no sense in JS unless those objects are property values of b: var b = {a: ObjectA, b: ObjectB}
yeah the value is like this b = {a:ObjectA, c: ObjectC, ...}
If a is an Array then try a.concat(Object.values(b)). This will concatenate the values from b to the a array.

let a = [];
let b = {a:1, b:2, c:3};
for(obj in b){
 let val = {};
 val[obj] = b[obj];
 a.push(val);
}
console.log(a);

Did you mean something like this ?

The Object.values() method returns an array of a given object's own enumerable property values,

You could use the Object values method Object.values() , like :

Object.values(b);

Example :

var a = [];
var obj_1 = {'attr_1': 'val_1', 'attr_2': 'val_2'};
var obj_2 = {'attr_3': 'val_3', 'attr_4': 'val_4'};
var b = {'a': obj_1, 'b': obj_2};
a = Object.values(b);
console.log( a );

Hope this helps.

Check my update, I got you, Object.values() is what you're searching for.
Is it really more beneficial in this case to create a third object to call Object.values() on rather than just: a.push(obj_1); a.push(obj_2);?...
Same result. The value of b is like: b = {a:ObjectA, c: ObjectC, ...}
What you mean by ObjectA and ObjectC ? give us a real case so we can understand more what you want to achieve
@user1012181 the Object.values(b) does the same thing that @Andre suggest in the accepted answer !!
