removeAllBeforeFirst(value, array):void

Removes everything before first instance of value in array.

removeAllBeforeLast(value, array): void

Removes everything before last instance of value in array.

For both, the parameter value cannot be an object. It can be an array.

Examples

let arr = [5, 10, 15, [20,22], 10, 50, [20,22], 60];  
removeAllBeforeFirst([20,22], arr);  
// arr is now [[20,22],10,50,[20,22],60]  

let arr = [5, 10, 15, [20,22], 10, 50, [20,22], 60]; 
removeAllBeforeLast([20,22], arr);  
// arr is now [[20,22], 60]
