限り sets a condition or scope, meaning 'as long as' or 'as far as'.
限り expresses a limit or condition under which something holds true. When it means 'as long as', it indicates that while the condition continues, the result is guaranteed. For example, 頑張る限り、夢は叶う means 'as long as you keep trying, your dream will come true.' It can also mean 'as far as', based on the speaker's knowledge or observation, as in 私が知る限り、彼は真面目だ ('as far as I know, he is serious').
