I can't believe this hasn't been posted yet: just use arrow-notation with anonymous evaluation!
Completely non-invasive, doesn't mess with the namespace, and it takes just one line:
myNewObj = ((k,v)=>{o={};o[k]=v;return o;})(myKey,myValue);
demo:
var myKey="valueof_myKey";
var myValue="valueof_myValue";
var myNewObj = ((k,v)=>{o={};o[k]=v;return o;})(myKey,myValue);
console.log(myNewObj);
useful in environments that don't support the new {[myKey]: myValue}
syntax yet, such as—apparently; I just verified it on my Web Developer Console—Firefox 72.0.1, released 2020-01-08.
(I'm sure you could potentially make some more powerful/extensible solutions or whatever involving clever use of reduce
, but at that point you'd probably be better served by just breaking out the Object-creation into its own function instead of compulsively jamming it all inline)
not that it matters since OP asked this ten years ago, but for completeness' sake and to demonstrate how it is exactly the answer to the question as stated, I'll show this in the original context:
var thetop = 'top';
<something>.stop().animate(
((k,v)=>{o={};o[k]=v;return o;})(thetop,10), 10
);
