2. Burauzar tana bincike shi da JSON.parse. Idan shigarwa ba JSON mai inganci ba ce, parser yana jefa SyntaxError wanda aka kama kuma aka fitar da shi da kansa — rubutun ka ba ya taba barin shafin.
3. Lokacin da bincike ya yi nasara, ana sake fitar da ƙima da aka bincike da JSON.stringify(value) — babu gardama na shinge — yana samar da mafi ƙanƙanta siffa mai inganci na ƙima guda ɗaya.
4. Ana ƙididdige tsawon byte na rubutun asali da na rubutun da aka rage da new TextEncoder().encode(...).byteLength — ƙididdigan baiti na UTF-8 guda ɗaya da maɓallin HTTP zai gani a waya.
