I'm trying to get the other item out of an array. I have an array called fruit and a variable called apples. I want to go through the array and find any other fruit apart from the one I already have.

Thanks in advance for any help

var fruit =  [
        "apples",
        "pears"
    ];

var alreadyHave = "apples";


for( var i = 0; i < fruit.length; i++){
    if (! fruit[i] === alreadyHave) {
        fruit.splice(i, 1); 
    }
}

console.log(fruit);

I would like to set the remaining fruit as another variable.

You can use the filter method for this:

const leftFruits = fruit.filter(f => f !== alreadyHave);

Simply use filter() function 

var fruit =  [
        "apples",
        "pears"
    ];

var alreadyHave = "apples";
console.log(fruit.filter(x => x !== alreadyHave))

You can use Array#filter to achieve this:

var alreadyHave = "apples";

var fruit = [
  "apples",
  "pears",
  "banana",
  "orange"
];

/* Create a new variable/array with all fruit items except for apples */
var remainingFruit = fruit.filter(item => alreadyHave !== item);

console.log(remainingFruit);

Use javascript filter() method for it

var fruit =  [
    "apples",
    "pears"
];

var alreadyHave = "apples";

var filteredFruit = fruit.filter(item => item !== alreadyHave);

let fruit = [ "apples", "pears" ];

let alreadyHave = "apples";

let fruitsExceptAlreadyHave = fruit.filter(element => element !== alreadyHave);
