I'm trying to access a state object property from a mutation in a Vuex Store but I can't find the right syntax :

Here is the state:

state: 
 events: [ 
 day: 8
 location: NY
 , 
 day: 9:
 location: NY
 
 ]
 

And here is the mutation :

SET_EVENT_LIST: (state, list) => 
 if(list.day < 10) 
 list.day = '0'+list.day
 

 state.events = list
 ,

I want to change the value of each event.day under 10. What am I doing wrong?

the right syntax should be like :

 const store = new Vuex.Store(
 state: 
 events: [ 
 day: 8
 location: "NY"
 , 
 day: 9,
 location: "NY"
 
 ]
 ,
 mutations: 
 SET_EVENT_LIST (state, list) 

 state.events = list.map(l=>
 if (l.day < 10) 
 l.day = '0' + l.day
 return l;
 
 else return l; 
 )
 
 
 )

Notes

• the values of location key should be strings


• 
  

  Each method in mutations should have this syntax :

  
  
  

   mutations:
   method_name(state,other_parameters)... 
   
  

  
  

or

 mutations:
 method_name:(state,other_parameters)=>... 
 

Map function example

let events = [
 day: 7,
 loc: "NY"
, 
 day: 8,
 loc: "NY"
, 
 day: 18,
 loc: "Paris"
];

let custom_events = events.map(l => 
 if (l.day < 10) 
 l.day = '0' + l.day
 return l;
 else return l;
);

console.log(custom_events);
