JavaScript Operators: Operators are used in all programming languages to do calculations, assign, compare and retrieve results from various functions and events. Similarly, JS uses operators to the same. Below are a few JavaScript operators:
Addition: JavaScript uses the sign + for addition of numeric values.
Example: 2+2 the result is 4 in JS.
Concatenation: JavaScript uses plus + sign for concatenating text values.
Example: “Johne” + “Ashbey” would return Johne Ashbey in JS.
Subtract: We use hyphen – sign for subtraction or minus in JavaScript.
Example: 4-2 would result in 2
Multiply: The language JavaScript applies asterisk(*) sign for multiplication.
Example: 4*2 should result 8 in JS.
Divide: JS has / forward slash or division symbol for dividing numbers.
Example: 8/2 will result in 4.
Assignment: Assigning a value to a variable is done using equal sign(=). But keep in mind that it assigns a value to a variable, it does not equate unlike == sign.
Example: var x = 10;
Identity Operator: JavaScript uses (==) double equal sign to check if one value is equal to another or not. The JS returns either true or false after the test is applied:
Example:
Var myScore = 10;
Var myScore == 20;
The above would reflect in JS as false.
