letfunction_array=["log","warn"];letfunction_to_run=1;// this would be dynamic index of arrayletcaller='console.'+function_array[function_to_run];let_1='first_parameter';let_2='Additional'+' Parameter'+'dynamically added';(newFunction(`${caller}('${_1}','${_2}')`))()
when function_to_run is 1, it will call console.warn, when it is 0, it will call console.log.

According to MDN docs, its not exactly eval. Every function in js is an object of Function class, so this is just manual work to implement same thing.
One drawback is that this will create an object everytime for execution and mark it for garbage collection, so if you have a fix set of functions that just needs to be called dynamically, use conditional logic like `if ('add') { this.add()}
For further actions, you may consider blocking this person and/or reporting abuse

Here is a working code
when function_to_run is 1, it will call console.warn, when it is 0, it will call console.log.
Ah it's so obvious now that you show me, eval type thing nice!!
