How to access an element of an array without using indexer (javascript)? -


let's have single element array ["somestringhere"] (i don't know in advance string be) , want access string function returns string , not array, how without using indexer (ex: array[0])?

in other words, if delete brackets had string.

every object has tostring method. go using method, though it's confusing why you'd want to. option join method.

var somearr = ['some string here'];  console.log(somearr.tostring()); console.log(somearr.join()); 

according mdn:

the array object overrides tostring method of object. array objects, tostring method joins array , returns 1 string containing each array element separated commas.

see here specifics.
