Fill/Map Array(N).fill().map((_, i) Step 3: Now iterate all the array items using JavaScript forEach and at each iteration, create a li element and put the innerText value the same as the current item, and append the li at the list. JavaScript Create Range Example Code. Some results are summarized on approximate string-matching with a string distance function that is computable in linear time and is based on the so-called q-grams ('n-grams').An algorithm is given for the associated string matching problem that finds the locally best approximate occurrences of pattern P, P = m, in text T, T = n, in time O(n log(m -
