Question

I have an unusual request. Given a string like the following:

var a = "This is a sentance that has many words. I would like to split this to a few lines"

I need to insert a “\n” every fifth word. The string a can have any number of alphanumeric characters.

Can someone give me an idea how I could do this?

Answer 1

a.split(/((?:\w+ ){5})/g).filter(Boolean).join("\n");
/*
    This is a sentance that 
    has many words. 
    I would like to split 
    this to a few lines
*/
