1 That is the modulo operator, which finds the remainder of division of one number by another. So in this case a will be the remainder of b divided by c.
The !! operator reassures the lint tool that what you wrote is what you meant: do this operation, then take the truth value of the result. A third use is to produce logical XOR and logical XNOR.
The strict equality operator (===) behaves identically to the abstract equality operator (==) except no type conversion is done, and the types must be the same to be considered equal. Reference: JavaScript Tutorial: Comparison Operators The == operator will compare for equality after doing any necessary type conversions. The === operator will not do the conversion, so if two values are not the ...
What are the differences between the assignment operators = and <- in R? As your example shows, = and <- have slightly different operator precedence (which determines the order of evaluation when they are mixed in the same expression). In fact, ?Syntax in R gives the following operator precedence table, from highest to lowest:
Ternary operator refers to any operator with three parameters, thus this is a ternary operator but not the ternary operator. Major languages (C#, Java, PHP) consider it a conditional operator, and call it the ?: operator. Occasionally (JavaScript) it is called the conditional operator.
I recently saw the above operator in a code,I googled for it but found nothing.The code is below.Please describe what actually does this operator do? #include<stdio.h> int main() { unsig...
It's called the "conditional operator" (sometimes not entirely accurately referred to as "the ternary operator", since it's the only ternary operator in C). It's not a statement though, it's an expression, it has a value.
The ?? operator was added to TypeScript 3.7 back in November 2019. And more recently, the ?? operator was included in ES2020, which is supported by Node 14 (released in April 2020). When the nullish coalescing operator ?? is supported, I typically use it instead of the OR operator || (unless there's a good reason not to).
