Integer ranges in JavaScript
To store data, various types of data types exist in every programming language. Data can be in the form of strings, characters, numbers, etc. For each type of data type, there is a certain limit on the allocated memory to use the memory efficiently, for example, a character is a small unit and an integer can be large compared to a character, so it is better to define characters differently than integers .
In order to use memory efficiently, various data types were created based on the memory they would occupy, which resulted in them having certain limitations on the characters they could store. This particular limit gives an upper limit on how many large numbers we can store in an integer.
Different types of numbers in JavaScript
Many programming languages divide numbers into different groups based on the size or presence of decimal digits. For example, in the C programming language, there are int data types for integers and float and decimal data types for non-integer real numbers, whereas in the python programming language, no such types exist.
In the JavaScript programming language, there are no different types of data types for numbers, the same data type exists for integers and floating point numbers.
There are now two types of ranges for numbers in JavaScript. The first is the maximum value that can be stored in a JavaScript variable, and the other is the safest value that can be stored in the JavaScript programming language.
Maximum integer value in JavaScript
The maximum integer value in JavaScript is the maximum value that can be stored in a JavaScript variable. The value is 1.79E 308.
There is a method in JavaScript, namely Number.MAX_VALUE, through which we can print the above value
Let us see the code to get the above value through the given function -
Example
// function to get the maximum value // that can be stored in the javascript variable function get_value() { console.log("The maximum value of the integer is: " + Number.MAX_VALUE); } get_value();
In the above code, we use the built-in method to get the maximum number that can be stored in an integer through the code of the JavaScript programming language.
Minimal positive integer value in JavaScript
The smallest integer value in JavaScript refers to the maximum number of digits we can get close to after the decimal point, which is the smallest floating positive number. The value is 5E-324, and although this number is low, it is still greater than zero.
There is a method in JavaScript, Number.MIN_VALUE, through which we can print the above value.
Let us see the code to get the above value through the given function -
Example
// function to get the minimum value // that can be stored in the javascript variable function get_value() { console.log("The minimum value of the integer which is greater than zero is: " + Number.MIN_VALUE); } get_value();
In the above code, we use the built-in method to obtain the smallest floating point number greater than zero through the code of the JavaScript programming language.
We've seen the two examples above that show the maximum and minimum positive integer ranges in which integers can be stored in JavaScript. Now let's move to this case and we'll see the maximum and minimum values of integers it can take and that it's safe too. Because it is not safe to handle large amounts of data.
Maximum positive safe integer value in JavaScript
The safe maximum integer value in JavaScript means that we can approach the maximum number of bits that is safe for computation in the JavaScript programming language. The value is 253 - 1.
There is a method in JavaScript, Number.MAX_SAFE_INTEGER, through which we can print the above value.
Let us see the code to get the above value through the given function -
Example
// function to get the maximum safe value // that can be stored in the javascript variable function get_value() { console.log("The maximum safe value of the integer which is greater than zero is: " + Number.MAX_SAFE_INTEGER); } get_value();
In the above code, we use the JavaScript programming language code to obtain the maximum safe positive integer, whose value is approximately 2 to the 53rd power, which is equivalent to 9E15.
Minimal negative safe integer value in JavaScript
Safe minimum integer value in JavaScript means the smallest number of bits we can approach that is safe for computation in the JavaScript programming language. The value is -(253 - 1).
There is a method Number.MIN_SAFE_INTEGER in JavaScript through which we can print the above value.
Let us see the code to get the above value through the given function -
Example
// function to get the minimum safe value // that can be stored in the javascript variable function get_value() { console.log("The minimum safe value of the integer which is greater than zero is: " + Number.MIN_SAFE_INTEGER); } get_value();
In the above code, we use the JavaScript programming language code to obtain the maximum safe positive integer, whose value is approximately negative 2 power 53, which is equivalent to the negative number of 9E15.
in conclusion
In this article, we learned about integer ranges in JavaScript programming language. Every line in the JavaScript code applies to the data the user wants to use and the data we need to store. In order to store data, various types of data types exist in every programming language. The data can be in the form of strings, characters, numbers, etc. The maximum value that can be stored in JavaScript is 1.79E 308 and the minimum value that can be stored in JavaScript is 5e-324. The maximum safe value is 2e53-1 and the minimum safe value is - (2e53-1).

Detailed explanation of JavaScript string replacement method and FAQ This article will explore two ways to replace string characters in JavaScript: internal JavaScript code and internal HTML for web pages. Replace string inside JavaScript code The most direct way is to use the replace() method: str = str.replace("find","replace"); This method replaces only the first match. To replace all matches, use a regular expression and add the global flag g: str = str.replace(/fi
