Javascript - How Do I Remove Objects From An Array That Contain A Specific String?

My array has several objects. Some of the objects contain a specific string, if the object contains this specific string I want it to be removed from the array. I tried to use a wh

Solution 1:

You can get the result using Array.filter

const value = [
  {name: "Timmy", status: "Smelly"},
  {name: "Tiffany", status: "Clean"},
  {name: "Kyle", status: "Smelly"},
  {name: "Space-man", status: "Clean"},
  {name: "Soap-man", status: "Clean"}
];

const result = value.filter((item) => item.status !== 'Smelly');
console.log(result);

Solution 2:

Use filter as:

let myArray = [
 {name: "Timmy", status: "Smelly"},
 {name: "Tiffany", status: "Clean"},
 {name: "Kyle", status: "Smelly"},
 {name: "Space-man", status: "Clean"},
 {name: "Soap-man", status: "Clean"},
 ]

let result = myArray.filter(i => i.status !== 'Smelly');
console.log(result)

Solution 3:

If you like to kee the object reference of the array, you could iterate from the end of the array.

Array#slice changes the indices if spliced from start.

let array = [{ name: "Timmy", status: "Smelly" }, { name: "Tiffany", status: "Clean" }, { name: "Kyle", status: "Smelly" }, { name: "Space-man", status: "Clean" }, { name: "Soap-man", status: "Clean" }],
    i = array.length;

while (i--) if (array[i].status === `Smelly`) array.splice(i, 1);

console.log(array);

.as-console-wrapper { max-height: 100%!important; top: 0; }

Solution 4:

Just filter it

You can choose to create a new filtered array or replace the existing one

let myArray = [ {name: "Timmy", status: "Smelly"}, {name: "Tiffany", status: "Clean"}, {name: "Kyle", status: "Smelly"}, {name: "Space-man", status: "Clean"}, {name: "Soap-man", status: "Clean"}]

// filter into a new arrayconst cleanArray = myArray.filter(item => item.status !== "Smelly")

console.log(cleanArray)
 
// or replace:
 
myArray = myArray.filter(item => item.status !== "Smelly")

console.log(myArray)

Solution 5:

First of all you need to have a boolean in the while loop. So you can add a counter starting from 0 and run the loop while the counter is less than the length of the array .

Here is the code:

let myArray = [
    { name: "Timmy", status: "Smelly" },
    { name: "Tiffany", status: "Clean" },
    { name: "Kyle", status: "Smelly" },
    { name: "Space-man", status: "Clean" },
    { name: "Soap-man", status: "Clean" },
]

let counter = 0;

while (counter < myArray.length) {
  let find = myArray.findIndex(i => i.status === `Smelly`);
  if (find != -1) {
    myArray.splice(find, 1);
  } else {
    counter++;
  }
}

myArray.forEach(el =>console.log(el));
