Cannot use string.match in js

Question

I have the following script, I need to return the following result:

{
      text: 'i love apples'
    }, {
      text: 'i eat my apple'
    }, {
      text: 'no apples on the table'
    }

with the following script I get an error.

What am I doing wrong, how to fix it (also another solution without using .match could be fine too)?

Notes: search value could be different, so script should be re-usuable.

let data = [{
  text: 'i love apples'
}, {
  text: 'i eat my apple'
}, {
  text: 'no apples on the table'
},{
  text: 'i love oranges'
}];
let search = 'apple'

let filter = data.filter(item=>{ return item.match(search)})
console.log(filter)

Are you looking for something more like item.text.match(search)? — Marc Baumbach

use includes instead and make sure to reference the property in your iteration.

let data = [{
  text: 'i love apples'
}, {
  text: 'i eat my apple'
}, {
  text: 'no apples on the table'
}, {
  text: 'i love oranges'
}];
let search = 'apple';

let filter = data.filter(item => item.text.includes(search))
console.log(filter)

Yep, and you can also safely omit return and braces

You are just there, use item.text.match. where item is iterator to your data array.

let data = [{
  text: 'i love apples'
}, {
  text: 'i eat my apple'
}, {
  text: 'no apples on the table'
},{
  text: 'i love oranges'
}];
let search = 'apple'

let filter = data.filter(item=>{ return item.text.match(search)})
console.log(filter)

The only thing I feel you are missing is the item.text, match is a function on string instead of object, you want to go one level deeper to match the content.

let data = [{
  text: 'i love apples'
}, {
  text: 'i eat my apple'
}, {
  text: 'no apples on the table'
},{
  text: 'i love oranges'
}];
let search = 'apple'

let filter = data.filter((item)=>{ return item.text.match(search)})
console.log(filter)
