let's i'm writing scala library l depends on dependency d , consumed program p , program q. p depends on version 3.2 of d directly while q depends on version 3.3 directly. between 2 versions d's api shuffled same function use in l, must write different import statements in l. likewise p relies on 3.2-specific behavior whereas q relies on 3.3-specific behavior. now, happen recent version of d chosen when compiling p , q, cause either p break if l depends on version 3.3 of library or l break when compiling q if l depends on version 3.2 of d. i ideally same version of l used both p , q since l's public api not change. possible? the general method comes mind conditional compilation of l based on dependency resolution. seems unachievable though in jvm world since don't transitively compile project's dependencies , instead rely on precompiled artifacts. i can right sbt if d scala (i.e. cross-compiling different scala versions , having version specific co...

is there way diff objects in immutable ? example: let = immutable.fromjs({ a: 10 }); let b = immutable.fromjs({ b: 10 }); let d = immutable.diff(a, b); // { a: 10 } console.log(d.tojs()); this useful when testing see how objects differ. it doesn't have show what's added/removed explicitly. want see properties a differs b can make them equal again. for example this: console.log(a.tojs()); console.log(b.tojs()); and check logs see differs b. in other thought might show both added , removed properties in same output. main point see not equal. so be: // { a: 10, b: 10 } console.log(d.tojs()); or maybe: // { added: { a: 10 }, removed: { b: 10 } } // console.log(d.tojs());

what difference between = , == , , === ? i think using 1 equal sign declare variable while 2 equal signs comparison condition , lastly 3 equal signs comparing values of declared variables. you have = assignment operator , == 'equal' comparison operator , === 'identical' comparison operator . $a = $b assign sets $a equal $b. $a == $b equal true if $a equal $b. $a === $b identical true if $a equal $b, , of same type. (introduced in php 4) for more info on need == , === , , situations use each, @ the docs .
