Question

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

Answer 1

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"]
