how to make a string to be part of a code in javascript?
0
For example if I have
var x = "console";
is it possible to run
x.log("Hello");
in javascript?
I ran it using window and eval but it wasn't working or is there a specific way to use those?

I recommend looking for an alternative to whatever problem you are trying to solve, so it doesn't involve evaluating arbitrary strings, it sounds neither safe nor performant.

Here are two ways of using a string to call the original function for console.
eval("console").log("hello world");
window["console"].log("hello world");If the string is "log" here is how it would work.
console["log"]("hello world");If you only wanted to use strings you could do something like so:
eval("console")["log"]("hello world");
window["console"]["log"]("hello world");
eval("console.log('hello world')");answered Nov 14 '18 at 20:59

ok. what if the string is "log" instead of "console"? would that still work?

in this case, you may have a look here: property accessor

@kemicofa Thank You so much!!! The code console["log"]("hello world"); worked for me. I was putting a dot after console this whole time.
