For example: 'Hello, ' + 'World!' // Hello, World! 'The number is ' + 42 // 'The number is 42' If one operand is a string, the other operand is also converted to a string, and then the two strings are concatenated. Once this is done, it examines the types of both operands. When evaluating expressions using the + operator, JavaScript first coerces both operands to primitive values. The addition operator performs two distinct operations: numeric addition and string concatenation. Beyond these, we also have the modulus operator ( %), which returns the remainder of a division operation, and the increment ( ++) and decrement ( -) operators that modify a value by one. The commonly used arithmetic operators in JavaScript include addition ( +), subtraction ( -), multiplication ( *), and division ( /). You can read more about truthy and falsy values in Truthy and Falsy Values: When All is Not Equal in JavaScript.Īs we explore JavaScript operators, we’ll see these concepts in action and get a better understanding of how they influence the results of our operations.Īrithmetic operators allow us to perform arithmetic operations on values and to transform data. Truthy values are those that evaluate to true in a Boolean context, while falsy values evaluate to false - with falsy values being false, 0, -0, '', null, undefined, NaN and BigInt(0). It’s a special value of the Number type that represents an invalid or unrepresentable numeric value. The primitive types in JavaScript are String, Number, BigInt, Boolean, undefined, Symbol or null. For example, JavaScript might change a number into a string, or a non-Boolean value into a Boolean. In JavaScript, operands can be of various types, such as numbers, strings, variables, or even more complex expressions.Ĭoercion is the process of converting a value from one primitive type to another. For example, in the expression 5 + 3, + is the operator (the action of addition), and 5 and 3 are the operands - the numbers being added together. If we think of an operator as a kind of action, the operand is what the action is applied to. (Method 8) Use an Image (for various).Before we dive in, let’s clarify a couple of terms that we’ll be using quite a bit:Īn operand is the item that operators work on. (Note that the format is 4 hexadecimal characters.) (Note that you can omit any leading zeros.) For example, in Microsoft Office applications (e.g. The important part is the hexadecimal number after the U+, which is used in various formats. (Method 7) Use the Unicode (for various, e.g. For example:Ĭtx.fillText(omCodePoint(x), 5, 5) On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x2260 to place the ≠ symbol on your canvas. (Method 6) Use the HTML Hex Code (for webpages and HTML canvas). (Method 5) Use the CSS Code (for webpages). (Method 4) Use the HTML Entity Code (for webpages). (Method 3) Use the HTML Decimal Code (for webpages). Simply hold down the Alt Key and type 8800. If you have a keyboard with a numeric pad, you can use this method. Press the "Copy" button, and then paste the symbol into your document. How To Insert the ≠ Symbol (Method 1) Copy and paste the symbol.Ĭlick on the ≠ symbol from the table above.
