![]() They allow you to edit any website locally in real time. = on my own?Īnswer: Learn Chrome’s DevTools ! DevTools (also known as Web Inspector) is a web developer’s best friend. In this case, it would return false, because a string is not the same data type as an integer. Earlier I mentioned that we will be using the numbers “55” and 55, except, “55” is not an integer, it is a string, whereas 55 is an integer because it is not encapsulated by quotation marks.įor example, this means that if you have the numbers 55 and “55” and try comparing them with the “=” operator that it will not only compare the contents of the two data or variables you pass to it, it will also compare the typeof variable or data it is. JavaScript counts anything that is in between the two quotation marks as a string. The “=” operator compares both content and type, whereas “=” compares only content. With “=”, JavaScript does not care what data type (string or integer) you pass to it as long as the content that you provided it with matches. The result will always return either true or false. This means that you can perform logic tests to see if one thing is equal to another thing. In JavaScript, the “=” operator is a comparison operator. First things first, we need to understand what operators are, as well as how they work in JavaScript. Plenty of people struggle with which of these two JavaScript operators you should use so don’t feel bad that you don’t know the difference. If you aren’t sure what the difference between = and = are in JavaScript, you aren’t alone. The Difference Between = and = In JavaScript Adjunct Prof at Columbia University Business School. Shifts a in binary representation b ( > bīitwise operators will perform their operation on the binary representation of the number provided to the operator, and will return a standard numerical value.Chris Castiglione Follow Co-founder of Console.xyz. Bitwise NOTing any number x yields -(x+1) Bits that are 0 become 1 and bits that are 1 become 0. ![]() ![]() Returns a 1 in each bit position for which the corresponding bits of either but not both operands are 1s. Returns a 1 in each bit position for which the corresponding bits of either or both operands are 1s. If either bit of one of the operands is 0, the corresponding bit of the result is also 0. Returns a 1 in each bit position for which the corresponding bits of both operands are 1s. ![]() Operatorīit operators work with 32 bit numbers. See Type casting - Unary statements to learn the casting behavior if either operand is not a number. Unary operators indicate if a value is positive or negative. The pre increment version adds one to the variable and returns the new value while the post increment adds one and then returns the initial value of the variable. ![]() The increment/decrement by one operators have pre and post versions that differ in what they return. Returns the remainder of a number divided by another number. See Type casting - Arithmetic statements to learn the casting behavior if either operand is not a number. Arithmetic operatorsĪrithmetic operators are used to perform arithmetic on numbers. Operators allow you to assign values to variables, compare values, and define conditional statements. ![]()
