function world(params){
//Code to be executed when the function is called.
}
world()
//Explaination
//'world' in the function is the name of the function.
//There are brackets after function name. Those are use to push parameters
//The forth line Calls the function named 'world'
You need to install js2py or requests-html packages to run the JavaScript program from Python
//example :
//javaScript function : squareofNum()
code in python :
import js2py
squareofNum = "function f(x) {return x*x;}"
result = js2py.eval_js(squareofNum)
print(result(5))
>>output : 25
// function call

const obj = {

get bar() {

}
};
let copy = Object.assign({}, obj);
console.log(copy);
// { foo: 1, bar: 2 }
// The value of copy.bar is obj.bar's getter's return value.
// This is an assign function that copies full descriptors
function completeAssign(target, ...sources) {

// By default, Object.assign copies enumerable Symbols, too
