javascript - Concise way of defining ES6 symbols? -


if want define multiple symbols in row, syntax little verbose:

const = symbol('a'),     b = symbol('b'),     c = symbol('c'); 

i came more concise way it:

const [a, b, c] = ['a','b','c'].map(key => symbol(key)) 

is concise way possible, or there dedicated syntax declaring multiple symbols i'm unaware of?

p.s. 'a' 'b' , 'c' arbitrary examples of course. realize 1 clever particular example ;)

it can concise as

const [a, b, c] = ['a','b','c'].map(symbol); 

there's no way skip abc tautology here because variable names should explicitly written, symbol description.

symbol descriptions helpful debugging. if can omitted (not recommended), becomes

const [a, b, c] = [,,].map(symbol); 

for fixed amount of variables. and

const [a, b, c, d /*, ... */] = function* () { for(;;) yield symbol() }(); 

for unlimited amount of variables.
