var jsonArray = ["test", "test1", "test2"];
var matchedValue = "test1";

I want to remove remove and (matchedValue) from the JsonArray. How can i delete and return rest of the string 

Expected output : ["test", "test2"];

What I am doing : 

var setValue = JSON.parse(fetchMethodJsonArray);
dataRemoved = setValue.filter(function(el) {
              return el != fetchValue;
          });

If you are using NodeJs, You can use 'modernarray' which is an small and simple npm package.

https://www.npmjs.com/package/modernarray

Install it by npm install modernarray

let modernarray = require('modernarray');
let myarray = [{
  "val": "One"
}, {
  "val": "Two"
}, {
  "val": "Three"
}];
let outputArray2 = modernarray.popByValue(myarray,{val:"One"})
console.log(outputArray2)

You can use this:

const deleteObj = (data, column, search) => {
    let result = data.filter(m => m[column] !== search);

    return result;
}

When you want to remove an object from JSON array element use this method:

const deleteObj = (data, column, search) => {
  let result = data.filter(m => m[column] !== search);

  return result;
}

const arr = [
  {
    name: 'test',
    surname: 'test1'
  },
  {
    name: 'test23',
    surname: 'newsname'
  },
  {
    name: 'test23',
    surname: 'newsname'
  }
]


const deleted = deleteObj(arr, 'name', 'test');
console.log(deleted);

In this sample, you will use filter method. Mozilla says about filter:

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

// Assuming this is your fetched data
const fetchMethodJsonArray = [{
  "val": "One"
}, {
  "val": "Two"
}, {
  "val": "Three"
}];


var setValue = fetchMethodJsonArray;
const dataRemoved = setValue.filter((el) => {
  return el.val !== "One";
});

console.log(dataRemoved);

Answer from what i got..

jsonArray.splice(jsonArray.indexOf('string_to_search'));

It will delete the found item and return remaining array.
