prepend to array javascript
// Build an array of test data. var data = [ "X" ]; // Unshift data onto the array. Unshift() prepends elements to // the beginning of the given array. Note that it can take more // than one argument. In the output, notice that when unshift() // takes multiple arguments, they are prepended in a right-to-left // order (mimicing their appearence in the arguments list). data.unshift( "A" ); data.unshift( "B", "C" ); // Output resultant array. console.log( data );
