What is a Programming Language?

● A programming language is a vocabulary and set of grammatical

rules for instructing a computer or computing device to perform

specific tasks.

● We can compare it with English language which we use for daily

communication.

● Just like English language, we have syntax(grammer), vocabulary(

keywords) to learn to write program( sentences) with which we can

build applications (Text book).

Key features:

● Statically typed

● Concise

● Safe

● Interoperable with Java

● Functional and Object Oriented

● High performance than JAVA

Statically typed Vs Dynamically typed:

● In statically typed programming languages, type checking

occurs at compile time. At compile time, source code in a

specific programming language is converted to a

machine-readable format. This means that before source

code is compiled, the type associated with each and every

single variable must be known.

● Some common examples of programming languages that

belong to this category are Java, Haskell, C, C++, C#, Scala,

Kotlin, Fortran, Go, Pascal, and Swift.

● In dynamically typed languages, type checking takes place

at runtime or execution time. This means that variables are

checked against types only when the program is executing.

● Some examples of programming languages that belong to

○ this category are Python, JavaScript, Lisp, PHP,

Ruby, Perl, Lua, and Tcl.
