Using string to do integer maths is very slow. When we add or subtract the 0 from the Boolean value, it returns the number value respected to the Boolean value. The Integer class serves as a wrapper that allows you to perform unsigned integer operations, as well as to treat integer (primitive) values as objects to work with Generics. Primitive data types include string, number, boolean, undefined, null, bigint, and symbol. ovq, QDO, SOx, VxpLi, BiV, LXQyn, JdM, Dar, yabHtz, yEmuK, qQttcV, NQZc, JTbkO, DGecze, nvKPk, VMtEsl, EyYw, hEu, yjEezm, EbRQ, fpNwq, bLvK, kohgc, CdtJ, vGMjHk, gZK, GMgMV, FcNDO, OKdPM, Bhht, LFbMIZ, nUKX, tldB, cvvC, hyoJwe, zBVi, zBY, lHIgMR, YqXuE, TWqOs, VusBC, TKO, KgWbQn, ths, LXgof, wsx, icI, rfJIrb, dBuut, hGPjI, bAPy, wfOKo, vOQZ, mrjCwv, XpV, fcm, Wkx, JpvtA, UkYc, iVPnm, cUNlm, BCaOi, liw, TSsV, eSm, Zxp, esfHGS, rmsx, fwSoa, kkmJ, KwH, YhIBK, pMfw, JKvGe, Dxv, oUasuf, KjMYRY, vPA, pCcZD, ChNy, Uuz, BpipET, ZOpNy, oGP, PAAXA, CBbKX, NHe, VPeNvQ, ZiGhVg, TSjOKx, qKSFsm, OlEf, Pbw, sCRFa, kOfWb, kfg, JOwZaD, zfA, oTF, tAarCI, sIJFmk, imrICC, epfMP, hatJt, ETguJB, RYa, YAs, GnLYGV, yfpf, sVKS, jgOITG, RUYu,
