Developer guidelines

  • Function-scoped JavaScript variable declarations (variables declared with var) should always be put at the top of the block. They are visible in the entire function in which they are declared, but we are anticipating the let block-scoped variables which will be available in the future. When let will become available in the most used browser versions, it will be easier for us to just replace var with let because the variable declarations will already be put in the corresponding block.
  • Function declarations, but not definitions, so declarations like function f(...) { ... }, should be put at the top of the block in which they are declared because they can be called (they are visible) also before their declaration in that block. (This is the new ES6 behavior. See here, here and here.).
