Is there any practical difference between Number() and + other than performance or intent?
Tried googling, tried searching for posts from other sites and asked AI but couldn’t find any practical or technical answer.
below code is from AI , in all cases the output is always same. Couldnt find any practical difference.
console.log(“Unary + Operator vs Number Constructor”);
`
type here
// Conversion of Numeric Strings
let str1 = "42";
console.log("Unary +: ", +str1); // Output: 42
console.log("Number: ", Number(str1)); // Output: 42
// Conversion of Non-numeric Strings
let str2 = "abc";
console.log("Unary +: ", +str2); // Output: NaN
console.log("Number: ", Number(str2)); // Output: NaN
// Handling Empty Strings
let str3 = "";
console.log("Unary +: ", +str3); // Output: 0
console.log("Number: ", Number(str3)); // Output: 0
// Handling Strings with Whitespace
let str4 = " ";
console.log("Unary +: ", +str4); // Output: 0
console.log("Number: ", Number(str4)); // Output: 0
// Handling Boolean Strings
let str5 = "true";
console.log("Unary +: ", +str5); // Output: NaN
console.log("Number: ", Number(str5)); // Output: NaN
// Handling Special Numeric Strings
console.log("Unary + Infinity: ", +"Infinity"); // Output: Infinity
console.log("Unary -Infinity: ", +"-Infinity"); // Output: -Infinity
console.log("Unary NaN: ", +"NaN"); // Output: NaN
console.log("Number Infinity: ", Number("Infinity")); // Output: Infinity
console.log("Number -Infinity: ", Number("-Infinity")); // Output: -Infinity
console.log("Number NaN: ", Number("NaN")); // Output: NaN
// Conversion of Boolean Values
console.log("Unary + true: ", +true); // Output: 1
console.log("Unary + false: ", +false); // Output: 0
console.log("Number true: ", Number(true)); // Output: 1
console.log("Number false: ", Number(false)); // Output: 0
