What are the differences between any vs Object in TypeScript?
Gutha Vamsi KrishnaIn this shot, we will go through the differences of two data types, any and Object.
any
Syntax
var variablename:any;
- TypeScript provides us with the data type
anyto use when we don’t know the type of data that the variable holds while writing code. - It may be the case that you are getting data from server, and you are not sure about data type of variable. If so, use
any.
var data:any;
- Or, if you are not sure which user might enter the data into this variable, then use
any.
var inputFromUser:any
Example
In the following code snippet, we created a variable data with type any, and then we assign the string Data from server to data.
// creating variable with any data type var data:any; //assigning string to data data = "Data from server" //priting data to console console.log(data)
We can re-assign different values of different data types to variable data.
// creating variable with any data type var data:any; //assigning string to data data = "Data from server" //priting data to console console.log(data) //reassigned with integer data = 10 console.log(data) //reassigned with boolean data = true console.log(data)
Object
Syntax
var a: Object
- TypeScript provides the datatype
Objectto store plain JavaScript objects. - Object contains
key-valuepairs separated by a comma,.
{
1:"apple",
2:"Banana"
}
Example
In the following example, we are creating a variable fruits with data type as Object, and assigning values to it in line 5.
//creating variable fruits of data type Object
var fruits:Object;
//assigning object to fruits
fruits = {
1:"Apple",
2:"Banana",
3:"Orange"
}
//pritintg fruits Object
console.log(fruits)We can access the values present in the Object with keys.
//creating variable fruits of data type Object
var fruits:Object;
//assigning object to fruits
fruits = {
1:"Apple",
2:"Banana",
3:"Orange"
}
//get value for key 1
console.log(fruits["1"])RELATED TAGS
