Tips and and tricks to understand programming language

Understand about Every Programming language

As we know that every programming language has same logic.

As a JavaScript developer with just a little programming experience, you can learn a new language in just a few days (sometimes less).

Some people love learning new programming languages. Other people can't imagine having to learn even one. In this article, I'm going to show you how to think like a coder so that you can confidently learn any programming language you want.

The truth is, once you've learned how to program, the language you use becomes less of a hurdle and more of a formality. In fact, that's just one of the many reasons educators say to teach kids to code early. Regardless of how simple their introductory language may be, the logic remains the same across everything else children (or adult learners) are likely to encounter later.

When experienced programmers sit down to learn a new language, they're looking for five things.2. Built-ins and conditionals2. Built-ins and conditionals On2. Built-ins and conditionals2. Built-ins and conditionalsce you know those five things, you're ready to start coding.

1. Syntax

The syntax of a language describes the structure of code. This encompasses both how the code is written on a line-by-line basis as well as the actual words used to construct code statements.
Like IF Else every programming has this logic but every language have different syntax.

2. Built-ins and conditionals

A programming language, just like a natural language, has a finite number of words it recognizes as valid. This vocabulary can be expanded with additional libraries, but the core language knows a specific set of keywords. Most languages don't have as many keywords as you probably think. Even in a very low-level language like C, there are only 32 words, such as **for, do, while, int, float, char, break, **and so on.

Knowing these keywords gives you the ability to write basic expressions, the building blocks of a program. Many of the built-in words help you construct conditional statements, which influence the flow of your program. For instance, if you want to write a program that lets you click and drag an icon, then your code must detect when the user's mouse cursor is positioned over an icon. The code that causes the mouse to grab the icon must execute only if the mouse cursor is within the same coordinates as the icon's outer edges. That's a classic if/then statement, but different languages can express that differently.

3. Data types

Code deals with data, so you must learn how a programming language recognizes different kinds of data. All languages understand integers and most understand decimals and individual characters (a, b, c, and so on). These are often denoted as int, float and double, and char, but of course, the language's built-in vocabulary informs you of how to refer to these entities.

Sometimes a language has extra data types built into it, and other times complex data types are enabled with libraries. For instance, Python recognizes a string of characters with the keyword str, but C code must include the string.h header file for string features.

4. Operators and parsers

Once you understand the types of data a programming language deals in, you can learn how to analyze that data. Luckily, the discipline of mathematics is pretty stable, so math operators are often the same (or at least very similar) across many languages. For instance, adding two integers is usually done with a + symbol, and testing whether one integer is greater than another is usually done with the > symbol. Testing for equality is usually done with == (yes, that's two equal symbols, because a single equal symbol is usually reserved to set a value).

There are notable exceptions to the obvious in languages like Lisp and Bash, but as with everything else, it's just a matter of mental transliteration. Once you know how the expression is different, it's trivial for you to adapt. A quick review of a language's math operators is usually enough to get a feel for how math is done.

You also need to know how to compare and operate on non-numerical data, such as characters and strings. These are often done with a language's core libraries. For instance, Python features the split() method, while C requires string.h to provide the strtok() function.

5. Functions

Code usually isn't just a to-do list for a computer. Typically when you write code, you're looking to present a computer with a set of theoretical conditions and a set of instructions for actions that must be taken when each condition is met. While flow control with conditional statements and math and logic operators can do a lot, code is a lot more efficient once functions and classes are introduced because they let you define subroutines. For instance, should an application require a confirmation dialogue box very frequently, it's a lot easier to write that box once as an instance of a class rather than re-writing it each time you need it to appear throughout your code.

You need to learn how classes and functions are defined in the programming language you're learning. More precisely, first, you need to learn whether classes and functions are available in the programming language. Most modern languages do support functions, but classes are specialized constructs common to object-oriented languages.
