remove item from array javascript

const array = [2, 5, 9];

console.log(array);

const index = array.indexOf(5);
if (index > -1) {
  array.splice(index, 1);
}

// array = [2, 9]
console.log(array); 

var array = ["Item", "Item", "Delete me!", "Item"]

array.splice(2,1) // array is now ["Item","Item","Item"]

let originalArray = [1, 2, 3, 4, 5];

let filteredArray = originalArray.filter((value, index) => index !== 2);

let someArray = [
               {name:"Kristian", lines:"2,5,10"},
               {name:"John", lines:"1,19,26,96"},
               {name:"Kristian", lines:"2,58,160"},
               {name:"Felix", lines:"1,19,26,96"}
            ];

someArray = someArray.filter(person => person.name != 'John');
