javascript - replace first occurrence of string after another string -

tried find in network without success..

let's have following string:

this string test lot of string words here string string there string here string.

i need replace first 'string' 'anotherstring' after first 'here', output be:

this string test lot of string words here anotherstring string there string here string.

thank help!

you don't need add g modifier while replacing first occurance.

str.replace(/\b(here\b.*?)\bstring\b/, "$1anotherstring");
