How to use the Double Tilde (~~) Operator In Javascript
You can use the double tilde (~~) operator in JavaScript to convert NaN to 0. The double tilde is a bitwise operator that performs a bitwise NOT operation twice, effectively converting non-numeric values to 0.
Example: In this example, the variable value is assigned the value NaN. The ~~ operator is then used to convert NaN to 0, and the result is stored in the variable result. Finally, the console.log statement prints the result, which will be 0.
Javascript
let value = NaN;let result = ~~value;console.log(result); // Output: 0 |
Output
0
