how can you change the value of an array in vue.js?

Question

how can you change the value of an array 'reactively' by using Vue.js

data:{
cafe:[
{dish:’chips’},
{dish:’smokies’},
{dish:’hotdogs’},
(juice:’mango’)
]
}

suppose you want to change "chips" to "fish"

Use $set for setting value.

this.$set(this.cafe[0],'dish','fish');

You could change your data structure a little bit, to make it more accessable.

data:{
  cafe: {
    dish: ["chips", "smokies", "hotdogs"],
    juice: ["mango"]
  }
 }

Then, you can filter a little bit easier.

this.cafe.dish = [...this.cafe.dish.filter(value => value !== "chips"), "fish"]

The dish array get's filtered and returns all values except chips, then you create a new array from the filter return and put in the fish.
