Using the shift() method in Javascript to manipulate Objects

My goal is to take my list and combine the first two items (0 & 1) together.

I attempted the following code: 

        total=foo.shift();
        foo[0]=total

However, I encountered this error:

Uncaught TypeError: Object [object Array] has no method 'split'

Even when I simply tried to call "foo" without modifications, I got the same error. This indicates that the array may not be easily workable without a workaround.

Any assistance on how to overcome this issue would be greatly appreciated. Thank you.

Answer №1

Here is a useful code snippet for you to refer to:

// Creating an array with two objects
var arr = [{'id':1,'name':'John'},{'id':2,'name':'Jane'}];
console.log(arr);
// Output: [{Object}, {Object}]

// Using the shift method to remove the first object
arr.shift();

console.log(arr);
// Output: [{Object}]
