Passing object key as javascript function argument
arguments, javascript, key-value, object, parameters
Solution
You can access a specific key with the array notation:
op_hours[key].push('shark')
where `key === "thu"` for example
would give you:
op_hours = {
"mon": ["apple","orange"],
"tue": ["table", "chair"],
"wed": ["shark", "dolphin", "jellyfish"],
"thu": ["shark"],
"fri": [],
"sat": [],
"sun": []
}
Problem
I have an object, op_hours, which has days of the week as keys from mon - sun, with arrays of strings as values (In my actual code the values are arrays of objects, but I have changed them to strings here for simplicity). How may I add/remove strings from a certain key by passing the required key into a function argument? For instance, ``` function add(somethingToAdd, op_hours, key) { var sample = op_hours.key; sample.push(somethingToAdd); op_hours.key = sample; return op_hours; } var op_hours = { "mon": ["apple","orange"], "tue": ["table", "chair"], "wed": ["shark", "dolphin", "jellyfish"], "thu": [], "fri": [], "sat": [], "sun": [] }; ``` I currently have to write 14 functions, seven for adding and seven for deleting as follows: ``` function addMon(miniObj, bigObj) { var sample = bigObj.mon; sample.push(miniObj); bigObj.mon = sample; return bigObj; }} ```
