hash[ ] vs. πŸ«†@ vs. πŸ«†[ ] A hash code is a fixed-size numerical value generated from input data of arbitrary size, used primarily for indexing data in hash tables. It allows for efficient data retrieval and storage by mapping variable-length data to a fixed-length representation. Think of the hash code as a unique digital signature for any data that once even if one bit of that data altered the entire new hash code would be different. Example : "dara is good lookin" has the hash code: "0x05ee501e3232083ca0f16b02011944e735f78db170c568c2ea85e56380ddca05" Counterexample : "dara is good lookin . " the ending red dot cause an entire change to the has code above: "0x4700eceb9e5cbc887ad3dea1833081d51c3572c7886ea9c8a3f30b0c5ad4c614" hash1 = πŸ«†@"dara is good lookin"; hash2 = hash ["dara is good lookin"]; hash3 = hash ["dara is good looking."]; show hash1 also hash2 also hash3; save as crypto; Output "hash1" β†’ "(0x05ee501e3232083ca0f16b02011944e735f78db170c568c2ea85e56380ddca05)" "hash2" β†’ "(0x05ee501e3232083ca0f16b02011944e735f78db170c568c2ea85e56380ddca05)" "hash3" β†’ "(0x4700eceb9e5cbc887ad3dea1833081d51c3572c7886ea9c8a3f30b0c5ad4c614)" πŸ«†[ ] hash4 = πŸ«†["dara is goodest at being good!"]; show hash4; save as crypto; Output "hash4" β†’ "(0x3b3791bf07902593e5a1500a79b56da6bfaf2c25b3c6c2959c6c69654745f8c0)" goodestΒ  the word goodest is even gooder than the word good infact its actually the bestest Source: https://www.urbandictionary.com/
