I'm currently refactoring my code and I want to export an object array called REFERENCE_LIST
to another file.
reference.js
export const REFERENCE_LIST = [
{name:"TypeA", foodList:foodAList},
{name:"TypeB", foodList:foodBList}
]
export const foodAList = ['apple', 'orange', 'banana']
];
export const foodBList = ['meat', 'fish']
];
However, the foodList
field from REFERENCE_LIST
is always "undefined". Am I referencing these arrays incorrectly?
You cannot reference variables in JS. You can reference object values, though - but those objects need to be created first for that:
export const foodAList = ['apple', 'orange', 'banana'];
export const foodBList = ['meat', 'fish'];
export const REFERENCE_LIST = [
{name:"TypeA", foodList:foodAList},
{name:"TypeB", foodList:foodBList}
];
You might also use getters where the order of creation doesn't matter:
export const REFERENCE_LIST = [
{name:"TypeA", get foodList() { return foodAList; }},
{name:"TypeB", get foodList() { return foodBList; }}
];
But even those will throw an exception when you evaluate them before the constants are initialised.
