Test name	Executions per second
inline func	30512.5 Ops/sec
bind func	17612.0 Ops/sec
custom bind	18441.5 Ops/sec

Script Preparation code:

var bind = (fn, ...args1)=> (...args2)=> fn(...args1, ...args2);

var foo_ = (a, b)=> a * b;

var foo1 = (a)=> (b)=> a*b;

var foo2 = (a)=> foo_.bind(undefined, a);

var foo3 = (a)=> bind(foo_, a)

Tests:

inline func
for(var i=0; i!==100; i++) { const ni = foo1(Math.random()); ni(Math.random()); }
bind func
for(var i=0; i!==100; i++) { const ni = foo2(Math.random()); ni(Math.random()); }
custom bind
for(var i=0; i!==100; i++) { const ni = foo3(Math.random()); ni(Math.random()); }
