Hello Dev,

In this example we will see how to push array element in node.js example. I will share some example about push object in array in node.js. node.js array element push, push element in array in node.js, node.js array push key value.

So, let's start to implement how to push array element in node.js

Example 1 : push() function

push() is an array function from node.js that is used to add element to the end of an array.

Syntax:

array_name.push(element)
push_array = [2, 4, 6, 8, 10, 12];
  
push_array.push(14);
  
console.log(push_array);

Output :

[ 2, 4, 6, 8, 10, 12, 14 ]

 

 

Example 2 : Key and Value

Now see key and value push in array object.

key_val_arr = [
    {id: 1, name: "dell" },
    {id: 2, name: "hp" },
    {id: 3, name: "apple" }
];
  
key_val_arr.push({id: 4, name: "lenovo"});
  
console.log(key_val_arr);

Output :

[

{ id: 1, name: 'dell' },

{ id: 2, name: 'hp' },

{ id: 3, name: 'apple' },

{ id: 4, name: 'lenovo' }

]

 

Example 3 : unshift() function

In this example add key and value in first position of array object using unshift() function.

key_val_arr = [
    { id: 1, name: "dell" },
    { id: 2, name: "hp" },
    { id: 3, name: "apple" }
];
  
key_val_arr.unshift({id: 4, name: "lenovo"});
  
console.log(key_val_arr);

Output :

[

{ id: 4, name: 'lenovo' },

{ id: 1, name: 'dell' },

{ id: 2, name: 'hp' },

{ id: 3, name: 'apple' }

]
