I wrote this code:

var arr = ['ясно','понятно']; var a = new RegExp(arr, 'i'); var b = 'ясно'; b.match(a);

For example, in the arr 2 array, the words: 'clear', 'clear', and these words can be searched separately. Those. separately: 'clear', separately: 'clear'.

How to set several words for search correctly and how to bring the code into working condition?

If you want to look for two words "clear" and "clear" with one regular expression, you can use the symbol | allows to implement logic in regular expressions OR

 var a = new RegExp('ясно|понятно', 'i');

using an array from your example, you can generate a regular expression by using the join() method

 var arr = ['ясно','понятно']; var a = new RegExp(arr.join('|'), 'i');
