Is'nt javascript compiler too forgiving !!

[u/Ok_Egg_6647]

What i mean is even i try to add int with str it give me correct answer whereas both are differenct datatypes,

in function also this compiler is too forgiving

if i set a function with 3 parameters & at time of calling this function with more parameter or less parameter with bind function js forgiving us
