how to remove an item by index from an array in javascript code example

Example 1: js remove item from array by value

var arr = ['bill', 'is', 'not', 'lame'];

arr.splice(output_items.indexOf('not'), 1);

console.log(arr) //returns ['bill', 'is', 'lame']

Example 2: delete from array javascript

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];var removed = arr.splice(2,2);/*removed === [3, 4]arr === [1, 2, 5, 6, 7, 8, 9, 0]*/

Example 3: remove one element using splice

fruits = ['Banana', 'Orange', 'Apple', 'Mango'];

removeFruitByIndex(index: number) {
  this.fruits = [
    ...this.fruits.slice(0, i),
    ...this.fruits.slice(i + 1, this.fruits.length),
  ];
}


removeFruitByValue(fruite: string) {
  const i = this.descriptionsList.indexOf(fruite);
  this.fruits = [
    ...this.fruits.slice(0, i),
    ...this.fruits.slice(i + 1, this.fruits.length),
  ];
}

Example 4: js delete all from array

var list = [1, 2, 3, 4];
function empty() {
    //empty your array
    list.length = 0;
}
empty();
