javascript - Best way to pass props for react component -

in react js can pass component props in 2 ways: <component prop1={value} prop2="value" prop3={this.othervalue} /> or let props = { prop1: value, prop2: "value", prop3: this.othervalue } <component {...props} /> what variant better? which prefer? neither "right", though think you're more see first variant, since seems bit clearer pass props explicitly. spread params variant used avoid duplication - if specify props on parent want pass them child, spelling them out explicitly on child feels bit laborious.

ruby on rails - Multiple Conditional Classes in HAML -

using ruby , haml, there shorter way represent logic: %tr{class: "#{'success' if admin.approved?} #{'warning' unless admin.approved?}"} thanks! you can simplify logic using ternary statement (one line if/else): %tr{class: admin.approved? ? 'success' : 'warning'} or move logic helper. example, create helper method in application_helper.rb : def admin_row_class(admin) admin.approved? ? 'success' : 'warning' end then use helper in view: %tr{class: admin_row_class(admin)}

Python String Formatting, difference in code -

hi trying understand how string formatting works float: i have tried >>> print("%s %s %s %s %-9.10f"%("this","is","monday","morning",56.3648)) it gives output of this monday morning 56.3648000000 however this, >>> print("%s %s %s %s %10f"%("this","is","monday","morning",56.3648)) gives output of this monday morning 56.364800 what causing difference? the way pattern strings parsed . %9.10f sets (minimum) field width 9 , precision 10, while %10f sets width 10. think meant write %.10f instead: in [4]: '%10f' % 56.3648 # width out[4]: ' 56.364800' in [5]: '%.10f' % 56.3648 # precision out[5]: '56.3648000000' also, consider using the newer str.format formatting style . first example turn into in [6]: '{} {} {} {} {:<9.10f}'.format('this', 'is', 'monday', 'mornin

haskell - Parsec how to find "matches" within a string -

how can use parsec parse matched input in string , discard rest? example: have simple number parser, , can find numbers if know separates them: num :: parser int num = read <$> many digit parse (num `sepby` space) "" "111 4 22" but if don't know between numbers? "i live 111 years <b>old</b> if work out 4 days week starting @ 22." many anychar doesn't work separator, because consumes everything. so how can things match arbitrary parser surrounded things want ignore? edit : note in real problem, parser more complicated: optiontag :: parser fragment optiontag = string "<option" manytill anychar (string "value=") n <- many1 digit manytill anychar (char '>') chapterprefix text <- many1 (noneof "<>") return $ option (read n) text chapterprefix = many digit >> char '.' >> many space for arbitrary

swift - Is it best practice to explicitly declare variable types on declaration? -

i new swift language, trying develop healthy programming habits while coding. is best practice explicitly declare variable types on declaration? example: var str:string = "likethis" or acceptable: var str= "likethis" as know, either option acceptable. however, standard practice have seen not declare variable types unless necessary, rationale these extraneous tokens reduce readability. here, unnecessary because compiler infer variable type. ray wenderlich's swift style guide agrees.
