Package Exports

toffee-script

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (toffee-script) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Code Examples

Left: ToffeeScript

Right: Generated JavaScript

Basic

x, y = a! b
console.log x, y

var x, y,
  _this = this;

a(b, function() {
  x = arguments[0], y = arguments[1];
  return console.log(x, y);
});

### Condition

if i
  x = a!
else
  y = b!
console.log x, y

var x, y, _$$_0,
  _this = this;

_$$_0 = function() {
  return console.log(x, y);
};
if (i) {
  a(function() {
    x = arguments[0];
    _$$_0();
  });
} else {
  b(function() {
    y = arguments[0];
    _$$_0();
  });
}

### Loop Support For In, For Of, While with guard `when`

xs = for i in [1..3] when i > 2
  a!

var i, xs,
  _this = this;

(function(_$cb$_0) {
  var _$res$_1, _body, _done, _i, _step;
  _$res$_1 = [];
  i = _i = 1;
  _step = function() {
    i = ++_i;
    _body();
  };
  _body = function() {
    if (i <= 3) {
      if (i > 2) {
        a(function($$_2) {
          step($res$1.push($$_2));
        });
      } else {
        _step();
      }
    } else {
      _done();
    }
  };
  _done = function() {
    _$cb$0($res$_1);
  };
  _body();
})(function() {
  return xs = arguments[0];
});

### Mathematics

x = a! + b! * c!

var x,
  _this = this;

(function(_$cb$0) {
  a(function($$1) {
    (function($cb$2) {
      b(function($$3) {
        c(function($$_4) {
          _$cb$2($$_3 * _$$4);
        });
      });
    })(function($$_5) {
      _$cb$0($$_1 + _$$_5);
    });
  });
})(function() {
  return x = arguments[0];
});

### Object

A =
  a: a
  b: b!
  c: c

var A,
  _this = this;

(function(_$cb$_0) {
  var _$$_1;
  _$$1 = a;
  b(function($$_2) {
    _$cb$_0({
      a: _$$_1,
      b: _$$_2,
      c: c
    });
  });
})(function() {
  return A = arguments[0];
});

### Logical Support `||`, `&&`, `?`, `&&=`, `||=`, `?=`

x = a! || b!
console.log x

var x,
  _this = this;

(function(_$cb$0) {
  (function($cb$3) {
    a(function($$1) {
      if ($$_1) {
        _$cb$3($$1);
      } else {
        b(function($$_2) {
          _$cb$3($$2);
        });
      }
    });
  })(function($$_4) {
    _$cb$0($$_4);
  });
})(function() {
  x = arguments[0];
  return console.log(x);
});

### Auto Callback

a = (autocb) -> return 3

var a;

a = function(autocb) {
  return autocb(3);
};

Return Multiple Values

a = (autocb) -> return null, 3

var a;

a = function(autocb) {
  return autocb(null, 3);
};

### Regexp

if a =~ b || b =~ c
  \~
  \&
  \0
  \9

var __matches;

if ((__matches = a.match(b)) || (__matches = b.match(c))) {
  __matches;
  __matches[0];
  __matches[0];
  __matches[9];
}
