I have a object of array stored in local-storage as shown below
var todos = [
{"id":0,"text":"Make lunch","completed":true},
{"id":1,"text":"Do laundry","completed":false},
{"id":2,"text":"Complete Project","completed":true}
]
How can i delete all objects that are completed? Please tell me how to delete it with splice method as i cant replace array i want to just remove it from array!(as my project requirements) Thanks for any help
You can try using the javascript array.filter
todos=todos.filter(todo=>!todo.completed);
You can filter uncompleted todos like:
const unCompletedTodos = todos.filter(todo => !todo.completed);
Also you don't have to use const you can use var but I recommend you to use const or let instead of var
var todos = [
{"id":0,"text":"Make lunch","completed":true},
{"id":1,"text":"Do laundry","completed":false},
{"id":2,"text":"Complete Project","completed":true} ];
var inCompletes = todos.filter(item => !item.completed );
inCompletes will return an array of objects with completed is false.
Output
inCompletes = [{"id":1,"text":"Do laundry","completed":false}];
Something like this would do the job
var filteredAry = todos.filter(function(e) { return e.competed !== 'true' })
"completed" is misspelled. But, secondly, you've put quotes around true.
