How does the functions differ from objects in Javascript? -


this question has answer here:

i have habit of using function id(_id) { return document.getelementbyid(_id); } lessen work of typing on , over.

sidenote:

jquery becomes heavy small tasks , projects

as learnt javascript more came know can pass around functions objects can do

var id = document.getelementbyid;

it seems both exact same thing. however, not expert in javascript, there difference internally? , preferred way of using?

yes, context is:

const log = console.log;  log("test");

the upper wont work because context changed, , log must called on console object, not on window ( aka without context). however, there easy workarounds:

const log = console.log.bind(console);

or use functions, example arrow ones:

const log = (...args) => console.log(...args);
