Script Preparation code:
var data = Array.from({ length: 10000 }).map((_, idx) => idx)
Tests:
spread insert
data.reduce((acc, val) => ({ ...acc, [val]: val }), {})
assign insert
data.reduce((acc, val) => Object.assign(acc, {[val]: val}))
map
Object.fromEntries(data.reduce((acc, val) => acc.set(val, val), new Map()))
mutation
data.reduce((acc, val) => acc[val] = val, {})
tuple
Object.fromEntries(data.map((v) => [v, v]))
