 What is the difference between a weak and strong type?

In a feebly wrote dialect, the sort of a quality relies on upon how it is utilized. For instance on the off chance that I can pass a string to the expansion admin and it will Automagically be deciphered as a number or reason a mistake if the substance of the string can't be made as a number. Likewise, I can connect strings and numbers or use strings as booleans, and so forth. 

In an unequivocally wrote dialect, a quality has a sort and that sort can't change. What you can do to a worth relies on upon the kind of the quality. 

The focal point of an emphatically wrote dialect is that you are compelled to make the conduct of your system unequivocal. In the event that you need to include a number and a string your code must decipher the string into a number to be utilized as an operand of the expansion specialist. This makes code less demanding to comprehend on the grounds that there is no (or less) concealed conduct. Be that as it may, it additionally makes your code more verbose. 

The focal point of a feebly wrote dialect is that you have to compose less code. Notwithstanding, that code is harder to comprehend in light of the fact that a ton of its conduct is stowed away in understood sort changes. 

I don't concur with that explanation as expressed. It's an exchange off. Verbosity additionally helps "harder to comprehend" for a lot of people. 

Solid vs. powerless writing is similar to static vs. element writing. In a statically wrote dialect, sort checking is performed at assemble time; in a dyamically wrote dialect sort checking is performed at run time. In practice, pitifully wrote dialects are normally alterably written. 

All dialects could be put some place in the 2d "writing" space whose tomahawks are solid <-> powerless and static <-> dynamic. E.g. sorts in Smalltalklanguage are extremely solid, totally dynamic; sorts in PHP are very feeble, totally dynamic; sorts in LISP are totally solid, totally dynamic; sorts in C are truly frail, totally static; etc... 

There are two separate issues that ought to be divided out: 

Could the sort be changed throughout run-time? 

Could the sort be constrained into something else effectively or certainly? Appear differently in relation to requiring an express change operation or watchword to transform it throughout run-time.
