`Quick Take`

`js import { strict as assert } from "assert";

import { matchLeftIncl, matchRightIncl, matchLeft, matchRight, } from "string-match-left-right";

// 3rd character is "d" because indexes start from zero. // We're checking the string to the left of it, "bcd", inclusive of current character ("d"). // This means, "bcd" has to end with existing character and the other chars to the left // must match exactly: assert.equal(matchLeftIncl("abcdefghi", 3, ["bcd"]), "bcd");

// neither "ab" nor "zz" are to the left of 3rd index, "d": assert.equal(matchLeft("abcdefghi", 3, ["ab", "zz"]), false);

// "def" is to the right of 3rd index (including it), "d": assert.equal(matchRightIncl("abcdefghi", 3, ["def", "zzz"]), "def");

// One of values, "ef" is exactly to the right of 3rd index, "d": assert.equal(matchRight("abcdefghi", 3, ["ef", "zz"]), "ef");``
