Replace string with values from two arrays

Question

I have a string for example:

var string = \'This is a text that needs to change\';

And then I have two arrays.

var array1 =         


        

Answer 1

Assuming your two arrays have the same size:

for(var i = 0; i < array1.length; i++){
    mystr = mystr.replace(array1[i], array2[i]);
}
