    var removed = productIds.splice(2,2);

    var list = ["bar", "baz", "foo", "qux"];
    
    list.splice(0, 2); 
    // Starting at index position 0, remove two elements ["bar", "baz"] and retains ["foo", "qux"].

Removing Array Items By Value Using Splice

   var productIds = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
    
    for( var i = 0; i < productIds.length; i++){ 
    
        if ( productIds[i] === 5) { 
    
            productIds.splice(i, 1); 
        }
    
    }
    
    //=> [1, 2, 3, 4, 6, 7, 8, 9, 0]

    var productIds = [1, 2, 3, 4, 5, 5, 6, 7, 8, 5, 9, 0];
    
    for( var i = 0; i < productIds.length; i++){ 
                                   
        if ( productIds[i] === 5) { 
            productIds.splice(i, 1); 
            i--; 
        }
    }

    //=> [1, 2, 3, 4, 6, 7, 8, 9, 0]
    

Using the Array filter Method to Remove Items By Value

    var productIds = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
    var filtered = productIds.filter(function(value, index, arr){ 
        return value > 5;
    });
    //filtered => [6, 7, 8, 9]
    //productIds => [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]

The Lodash Array Remove Method

var productIds = [1, 2, 3, 4];var evens = _.remove(productIds, function(n) { return n % 2 === 0;});console.log(productIds);// => [1, 3]console.log(evens);// => [2, 4]

Making a Remove Method

    function arrayRemove(productIds, value) { 
    
        return productIds.filter(function(ele){ 
            return ele != value; 
        });
    }
    
    var result = arrayRemove(array, 6);
    // result = [1, 2, 3, 4, 5, 7, 8, 9, 0]

Explicitly Remove Array Elements Using the Delete Operator

    var productIds = [1, 2, 3, 4, 5, 6];
    
    delete productIds[4]; // delete element with index 4
    
    console.log( productIds ); 
    
    // [1, 2, 3, 4, undefined, 6]
    
    alert( productIds ); 
    
    // 1,2,3,4,,6

Clear or Reset a JavaScript Array

var productIds = [1, 2, 3, 4, 5, 6];
//do stuffar = [];
//a new, empty array!

Example

var productIds = [1, 2, 3, 4, 5, 6];
var productIds2 = productIds; 
    // Reference productIds by another variable productIds = [];
    
console.log(productIds2); 
// Output [1, 2, 3, 4, 5, 6]

Example

var productIds = [1, 2, 3, 4, 5, 6];

console.log(productIds); 
// Output [1, 2, 3, 4, 5, 6]

productIds.length = 0;

console.log(productIds); 

// Output []

Example

var productIds = [1, 2, 3, 4, 5, 6];

console.log(productIds); 
// Output [1, 2, 3, 4, 5, 6]
productIds.splice(0, productIds.length);
console.log(productIds); 
// Output []

Example

var productIds = [1, 2, 3, 4, 5, 6];

console.log(productIds); 
// Output [1, 2, 3, 4, 5, 6]
