I've an array like:
a=[{'test':1,'test2':'2'},{'test':3,'test2':'4'}]
I'm trying to reduce this array to one object
Expected output
{1:2,3:4}
I've tried:
let newObj = a.reduce((pre,curr)=>Object.assign({},{curr.test:curr.test2}))//unexpected token at .
let newObj = a.reduce((pre,curr)=>Object.assign({},{curr['test']:curr['test2']}))//unexpected token at [
P.S: I have already achieved what I'm trying by not using arrow functions, I want to know why the above methods doesn't work
