     37 ## Usage
     38 
     39 ```javascript
     40 var funseq = require( '@stdlib/utils/function-sequence' );
     41 ```
     42 
     43 #### funseq( ...fcn )
     44 
     45 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.
     46 
     47 ```javascript
     48 function a( x ) {
     49     return 2 * x;
     50 }
     51 
     52 function b( x ) {
     53     return x + 3;
     54 }
     55 
     56 function c( x ) {
     57     return x / 5;
     58 }
     59 
     60 var f = funseq( a, b, c );
     61 
     62 var z = f( 6 ); // ((2*x)+3)/5
     63 // returns 3
     64 ```
     65 
     66 **Only** the leftmost function is explicitly permitted to accept multiple arguments. All other functions are evaluated as **unary** functions.
     67 
     68 ```javascript
     69 function a( x, y ) {
     70     return (x*5) + (y*3);
     71 }
     72 
     73 function b( r ) {
     74     return r + 12;
     75 }
     76 
     77 var f = funseq( a, b );
     78 
     79 var z = f( 4, 6 );
     80 // returns 50
     81 ```

     91 ## Notes
     92 
     93 -   The function will throw if provided fewer than `2` input arguments.
     94 -   The difference between this function and [`compose`][@stdlib/utils/compose] is that this function evaluates input arguments from left-to-right, rather than right-to-left.
