     37 ## Usage
     38 
     39 ```javascript
     40 var ifthen = require( '@stdlib/utils/if-then' );
     41 ```
     42 
     43 #### ifthen( bool, x, y )
     44 
     45 If a condition is truthy, invokes `x`; otherwise, invokes `y`.
     46 
     47 ```javascript
     48 function x() {
     49     return 1.0;
     50 }
     51 
     52 function y() {
     53     return -1.0;
     54 }
     55 
     56 var z = ifthen( true, x, y );
     57 // returns 1.0
     58 
     59 z = ifthen( false, x, y );
     60 // returns -1.0

     71 ## Notes
     72 
     73 -   The function is similar to [`ifelse()`][@stdlib/utils/if-else], but allows deferred argument evaluation.
