Sometimes, we want to filter an array of objects that contains a string using Lodash and JavaScript.

In this article, we’ll look at how to filter an array of objects that contains a string using Lodash and JavaScript.

How to filter an array of objects that contains a string using Lodash and JavaScript?

To filter an array of objects that contains a string using Lodash and JavaScript, we can use the string includes method.

For instance, we write:

const collection = [{
    val: "CPP@4@1900-01-01"
  },
  {
    val: "CMIP@5@1900-01-01"
  },
  {
    val: "CMIP@6@1900-01-01"
  },
  {
    val: "CMIP@7@1900-01-01"
  },
  {
    val: "CPP@8@1900-01-01"
  },
  {
    val: "CMIP@9@1900-01-01"
  },
  {
    val: "CMIP@10@1900-01-01"
  }

];
const search = 'CPP@';
const results = _.filter(collection, (item) => {
  return item.val.includes(search);
});
console.log(results);

to call filter with the collection to filter and a callback that returns the condition of the items we want to return.

We use includes to check if item.val has search inside.

Therefore, results is:

[
  {
    "val": "CPP@4@1900-01-01"
  },
  {
    "val": "CPP@8@1900-01-01"
  }
]

Conclusion

To filter an array of objects that contains a string using Lodash and JavaScript, we can use the string includes method.
