Javascript - object key->value

Question

var obj = {
   a: \"A\",
   b: \"B\",
   c: \"C\"
}

console.log(obj.a); // return string : A

but i want to get by through a variable like this

Answer 1

Use this syntax:

obj[name]

Note that obj.x is the same as obj["x"] for all valid JS identifiers, but the latter form accepts all string as keys (not just valid identifiers).

obj["Hey, this is ... neat?"] = 42
