Scala is a multi-paradigm programming language that combines the features of object-oriented programming and functional programming. Here are some of the basic syntax of Scala:

Define variables and constants:

Use the var keyword to define mutable variables and the val keyword to define immutable constants.

Example: Crawler IP Address

var x:int=10

val y:string="hello"

Data types: Scala provides a variety of data types, including integer, floating-point, boolean, and character.

Example: val a:int=10

val b:double=3.14

val c:boolean=true

val d:char='a'

Function definition: You can use the def keyword to define a function, and you can specify the parameters and return type.

Example: def add(x:int,y:int): int=

Control Flow Statement:

Scala supports if-else conditional statements and match-case statements.

Example: val age=20

if(age<18)else

Collections: Scala provides a wide range of collection classes, including lists, arrays, maps, and more.

Example: val list:list[int]=list(1,2,3,4,5).

val map:map[string,int]=map("a"->1,"b"->2,"c"->3)

Classes and objects: Scala is an object-oriented language where you can define classes and objects to organize.

Example: class person(name:string,age:int).

val person=new person("alice",25)

person.greet()

These are just some of the basic syntax of Scala, and there are many other features and syntax of Scala, such as pattern matching, higher-order functions, implicit transformations, etc.
