var fruit = [apple,pear,pear,pear,banana];

How do I remove all pear fruit from this array?

I tried the following, but still one pear remains:

for(var f in fruit) {

    if ( fruit[f] == pear ) {

        fruit.splice(f, 1);

    }

}



for(var f in fruit) {

    document.write(fruit[f]+<br>);        

}

Outputs:

apple 

pear 

banana

var fruit = [apple, pear, pear, pear, banana],

    i;



for (i = 0; i < fruit.length; ++i) {

    if (fruit[i] === pear) {

        fruit.splice(i--, 1);

    }

}



console.log(fruit);

//[apple, banana]
