If we have an array like this:
var arr = [ "one", "two", "three" ];
What is a more efficient method to convert it to:
{ "one": true, "two": true, "three": true }
I attempted the approach below, but I believe there could be a better solution.
_.zipObject(arr || {}, _.fill([], true, 0, arr.length))
const newObj = array.reduce((o, value) => { return o[value] = true, o; }, {});
Implementing the code with Lodash:
const newArr = ['apple', 'banana', 'cherry'];
_.mapValues(_.keyBy(newArr), () => false);
Here is an easy solution for achieving the same result:
function convertToArrayToObject(array) {
var obj = {};
for (var j = 0; j < array.length; ++j)
obj[j] = true;
return obj;
}
let fruits = ["apple", "banana", "orange"];
let myMap = new Map();
for (let i = 0; i < fruits.length; i++) {
myMap.set(fruits[i], true);
}
