When comparing a string with a number, JavaScript will convert the string to a number when doing the comparison. An empty string converts to 0. A non-numeric string converts to NaN which is always false. When comparing two strings, "2" will be greater than "12", because (alphabetically) 1 is less than 2. Bit operators work on 32 bits numbers. Any numeric operand in the operation is converted into a 32 bit number. The result is converted back to a JavaScript number. The examples above uses 4 bits unsigned examples. But JavaScript uses 32-bit signed numbers. Because of this, in JavaScript, ~ 5 will not return 10. It will return -6. JavaScript also contains a number of operators that don't fit into any other category, and it calls them special operators . I'll take a look at them here. I'll take a look at them here.

JavaScript has both binary and unary operators, and one special ternary operator, the conditional operator. A binary operator requires two operands, one before the operator and one after the operator: operand1 operator operand2 For example, 3+4 or x*y. Javascript Operators JavaScript includes operators same as other languages. An operator performs some operation on single or multiple operands (data value) and produces a result. For example, in 1 + 2, the + sign is an operator and 1 is left side operand and 2 is right side operand. Basic operators, maths. We know many operators from school.

Assignment operators (JavaScript) An assignment operator assigns a value to its left operand based on the value of its right operand. The basic assignment operator is equal (=). The other assignment operators are shorthand for another operation plus the assignment. Comparison operators (JavaScript) Comparison operators compare two values and yield a logical (boolean) result. Arithmetic operators (JavaScript) Lists can be processed as entities by certain operators. Special operators (JavaScript) A number of special operators are available.
