It can embed other values and functions inside it which quotes can’t do. *The strings that are inside back ticks(``) are called as template literals. The additional 3 bytes is because ES6 adds support for Unicode code point escapes. ES6 (ECMAScript 6) and later Versions: 2 or 5 bytes per character.When a character followed by a ‘\’ it becomes a escape sequence or character. Escape Character or sequence is a concept which is followed by almost all major modern programming languages.Strings can be triggered using back ticks (``), single quotes (‘’) or double quotes (“”).There are other operators such as Bitwise Operators and Comparison Operators for a detailed table you can refer the MDN Docs for Operator Precedence.However where does the other operators fall in? Well the logical operators take less precedence over arithmetic operators (except Logical NOT). It is something that fairly easy to remember for arithmetic operators and most easy trick is the BODMAS rule.They are represented as such ‘&’ for AND, ‘||’ for OR and ‘!’ for NOT. Logical Operators are of 3 types AND, OR, NOT.For ex- 314 % 100 produces 14 as the result. It essentially does is return the remainder. What might be new to you as a newbie program is the modulus (%) operator.The final code is something like this: /. If the property of the two objects is also an object, we use the current function to check their properties inequality, else we use the operator. These are the basic addition (+), subtraction (-), multiplication (*) and division (/). We are writing a function that checks if objects are equal. Arithmetic Operators are what you have been using almost all your life.JavaScript numbers are always stored as double precision floating point numbers, following the International IEEE 754 standards.Įnter fullscreen mode Exit fullscreen mode.But within that 64 bits we also have to represent negative numbers and decimal points as well, so the first bit is the sign bit and each decimal point takes a bit, that makes the representation of numbers somewhat close to 9 Quadrillion which is still a pretty big number.With 64 bits we can represent 264 numbers which equal to 18 Quintilian. JavaScript uses fixed number of bits to represent a single number, 64 of them t be precise. In JavaScript Numbers (integers) is anything from a whole number to decimal points to exponents.Not delving too deep into what bits, bytes and terabytes, I’m just going to say they are the ways information is stored in a computer’s memory, they take up space and when you delete something they are freed from the information they were holding. ![]() This blog will be a review of Chapter 1 of the book. ![]() After the introduction chapter down, here is the second part of the Eloquent JavaScript series.
