Changing the join funcion

#1

Array.prototype.joinOriginal = Array.prototype.join

Array.prototype.join = function() {
console.log(‘join called on’, this)
return this.joinOriginal(arguments)
}
let l=[123,234,345,445]
l.join(’;’)

when I am doing the above thing at console I am getting
an infinite output ex:

join called on 1[object Arguments]2[object Arguments]3[object Arguments]4

join called on 1[object Arguments]2[object Arguments]3[object Arguments]4

join called on 1[object Arguments]2[object Arguments]3[object Arguments]4

like this plz resolve it sir

@aggarwalanshul01 problem with your code is that, you have to expand the arguments using triple dot syntax, try the following code and it will work
return this.joinOriginal(...arguments)

@aggarwalanshul01 here is the working code

Array.prototype.joinOriginal = Array.prototype.join

Array.prototype.join = function() {
    console.log('join called on', this)
    return this.joinOriginal(...arguments)
}
let l=[123,234,345,445]
l.join(';')

try this after clearing of the history from the console
