I have object which contains array and I want it contains the associative array so keys are strings. How to do it? This does not work:
{profiles: { easy:["example" : 1],advanced:["example" : 1] }
I wanted to avoid
console.log({profiles: { easy:{"example" : 1},advanced:{"example" : 1} })
Because that easy and advanced members are not displayed as array but as object.
Another way I know is this:
array['key2']='new value';
but that is not part of the object so I would need to split command for multiple lines - which is not what I want.
PHP has something like array( "mykey" => "myValue" ), but does JavaScript have something similar?
Yet I don't want to use frameworks, this is JavaScript only.
JavaScript doesn't have "associative arrays".
It has objects, which you can store values on in named properties.
It has arrays, which store an ordered set of values via integer properties. Since they are a type of object, you can also store named values on them (but you can't create them using the literal syntax, only add them after the array is created) but this isn't considered good practise and they will be ignored by just about anything that has special case handling for arrays.
As of ES6 it also has Maps which are similar to objects in that you can give them named values, but also to arrays in that order is preserved. There is no literal syntax for creating a Map.
wanted to avoid
console.log({profiles: { easy:{"example" : 1},advanced:{"example" : 1} })
Why, is there a reason to avoid language specific features?
If I told you you can do this: (should be avoided)
var array = [];
array["foo"] = "bar";
array.foo // -> bar
The problems with it:
array.length // -> 0
So, even if you can apply properties to mostly everything in js like:
var str = "hello";
str.type = "greetings";
you shouldn't screw the language..
This is the normal way of creating key:value maps, objects.
var obj = {foo: "bar"}
obj.foo // -> bar
Why not doing it, just like the language is designed to?
