javascript - Price String spliting into amount and currency -

i need splitting string in javascript. i have string currency. string depends on location. for example: "1,99€" or "$1,99" i split string , extract "amount" , "currency" out of it. if fails, return empty string or null. does know how solve that? if expect inputs include both decimals of cent value (ie, comma followed 2 digits) use this: const amount = money.match(/\d/g).join('') / 100; const curren = money.match(/[^\d,]/g).join(''); javascripts hated implicit type coercion allows divide string numerator number denominator , end number. to currency, extract non- digit or comma characters , join them. if can't rely on input including cent value (ie, might receive whole dollar amount without comma or cent digits) try this: const amount = money.match(/d/g).join('') / (money.includes(',') ? 100 : 1);

using javascript, there difference in terms of performance or behavior between let foo = { a: true, b: false, c: true } 'c' in foo , foo['c'] ? always wondered that, not sure how search answer. obvious difference foo['c'] return false if 'c' points falsy value, 'c' in foo return true if foo has key 'c'. the reason ask question: in many cases want store key (for quick search) , not care value: let foo = { // keys important, values of no consequence a: undefined, b: undefined, c: undefined } i wondering if best practice store keys, without assigning value. if(!('a' in foo)){ foo['a'] = undefined; } it seems strange give hash values, when don't need use values, need store key. you answer own question the obvious difference foo['c'] return false if 'c' points falsy value, 'c' in foo return true if foo has key 'c'. ...

Why Android View class has 'outValues style' getters for handful of properties? -

you can view properties height , alpha , id , matrix , drawingtime or elevation using standard getters (like getheight() , getalpha() , getid() ...). but then, have of view's properties (most of them point or rect return type) locationinwindow , globalvisiblerect , locationinscreen , drawingrect , drawingcache hidden under getters forcing create returning objects beforehand empty constructor, , pass objects getter parameter data being 'saved' them. example of getter globalvisiblerect : public final boolean getglobalvisiblerect(rect r) forces (kotlin): val rect = rect() getglobalvisiblerect(rect) dosomestuffwithrect(rect) it's not consistent, nor debuggable in realtime expressions tab in android studio , it's cumbersome, really. why done way? see of methods returning false boolean value if view not visible, know returned data invalid, shouldn't solved returning null value, if method knows produced unusable information? on other hand, getlo...
