This is the object I have:
years = {1924:2, 1934: 10, 2010: 4}
I would like to transform this into:
years = [{year: 1924, items: 2}, {year: 1934, items: 10}, {year: 2010, items: 4}]
This is the code I came up with so far (which obviously doesn't work):
var years2 = {};
for (var i = 0; i < years.length; ++i) {
years2.push({ years: [$key] })
};
I am stuggling to find the right way to access the unnamed keys and map these into their own objects.
(I am still learning JS and I know this is basics, but somehow cannot get my head around it.. )
You can create key value pairs from the object with Object entries and map them to new array
const years = {1924:2, 1934: 10, 2010: 4}
const ans = Object.entries(years).map(([key,value]) => {
return {year: key, items: value}
})
console.log(ans);You can get entries, then convert to object with map
const years = {1924:2, 1934: 10, 2010: 4}
const result = Object.entries(years).map(([year, items]) => ({year: year, items: items}))
console.log(result)
