My microservice is providing me with a series of boolean values.
"mon": true,
"tues": false,
"wed": false,
"thurs": true,
"fri": false,
"sat": true,
"sun": false,
I want to take the values marked as true and convert them into an array like this:
options = ['mon', 'thurs', 'sat']What would be the best approach to accomplish this task?
To filter out the days key from an object, you can utilize the filter method:
var week = {
"mon": true,
"tues": false,
"wed": false,
"thurs": true,
"fri": false,
"sat": true,
"sun": false
};
var filteredDays = Object.keys(week).filter(day => week[day]);
console.log(filteredDays);If you want to narrow down the keys:
const obj = {
"summer": true,
"autumn": false,
"winter": false,
"spring": true,
};
const selectedSeasons = Object.keys(obj).filter(key => obj[key]);
console.log(selectedSeasons);Exploring a new method of working with entries and array breaking down 🚀🚀
let week = {
"mon": true,
"tues": false,
"wed": false,
"thurs": true,
"fri": false,
"sat": true,
"sun": false
};
let selectedDays = Object.entries(week).filter(([key, state]) =>state).map(([key]) => key);
console.log(selectedDays);I'm trying to merge two npm scripts into one, but the result is incorrect and causes issues with passing flags. I can't use the dotenv package, and using ampersands isn't solving the problem. Here's what I have in my package.json file ...
