Function sequence.
var funseq = require( '@stdlib/utils/function-sequence' );
Returns a pipeline function. Starting from the left, the pipeline function evaluates each function and passes the result as an argument to the next function. The result of the rightmost function is the result of the whole.
function a( x ) {
return 2 * x;
}
function b( x ) {
return x + 3;
}
function c( x ) {
return x / 5;
}
var f = funseq( a, b, c );
var z = f( 6 ); // ((2*x)+3)/5
// returns 3
Only the leftmost function is explicitly permitted to accept multiple arguments. All other functions are evaluated as unary functions.
function a( x, y ) {
return (x*5) + (y*3);
}
function b( r ) {
return r + 12;
}
var f = funseq( a, b );
var z = f( 4, 6 );
// returns 50
2
input arguments.compose
is that this function evaluates input arguments from left-to-right, rather than right-to-left.var funseq = require( '@stdlib/utils/function-sequence' );
function a( x, y ) {
return x * y;
}
function b( z ) {
return z + 5;
}
function c( r ) {
return r / 10;
}
var f = funseq( a, b, c );
var v = f( 5, 3 );
// returns 2
