Tricks

This document contain the simple yet important tricks to remember when dealing with strings or objects.

1. Convert any string to array simply by a single function.

Use split("", limit{any number})

//code const str = 'abra ka dabra' console.log(str.split(' ', 2)) output [ 'abra', 'ka' ]

2. Add properties to js objects dynamically

Use (.) operator

//code const dynamicObject = { name: 'Himanshu', age: 22 }; dynamicObject.sex = 'Male'; console.log(dynamicObject); //output { name: 'Himanshu', age: 22, sex: 12 }

3. Adding properties of a previous object to new object

 //code const object1 = { name : 'Himanshu', age : 22 } const newObject = {}; newObject.name = object1.name; newObject.age = object1.age; newObject.sex = 'Male'; console.log(newObject); //output { name: 'Himanshu', age: 22, sex: 'Male' }
