download javascript code example
Example 1: java
An incredible language that receives far more hate than it deserves
because of it's poor beginnings.
Everyone remembers the slow java applets but often fail to understand
Java's many positives including:
- compatability with many different systems
- Just-In-Time compilation making it almost as fast as a native language
- the wide range of high-quality and open source libraries developed over
many years
Sure, it may not look as sexy as Python or NodeJS, but when you're
debugging the call stack 50 functions deep, you'll be glad you picked Java
Example 2: javascript ...
function sum(x, y, z) {
return x + y + z;
}
const numbers = [1, 2, 3];
console.log(sum(...numbers));
// expected output: 6
console.log(sum.apply(null, numbers));
// expected output: 6
/* Spread syntax (...) allows an iterable such as an array expression or string
to be expanded in places where zero or more arguments (for function calls)
or elements (for array literals) are expected, or an object expression to be
expanded in places where zero or more key-value pairs (for object literals)
are expected. */
// ... can also be used in place of `arguments`
// For example, this function will add up all the arguments you give to it
function sum(...numbers) {
let sum = 0;
for (const number of numbers)
sum += number;
return sum;
}
console.log(sum(1, 2, 3, 4, 5));
// Expected output: 15
// They can also be used together, but the ... must be at the end
console.log(sum(4, 5, ...numbers));
// Expected output: 15
