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' }
