ES6: Spread Element (for function argument) #1169
Comments
Spread is not just allowed in function argument position, but also as an array initialiser element. [...a] |
As i see it, spread operator is not supported for the function calls. Arrays and fd are. |
So for the expression {
"type": "Program",
"body": [
{
"type": "ExpressionStatement",
"expression": {
"type": "CallExpression",
"callee": {
"type": "Identifier",
"name": "a"
},
"arguments": [
{
"argument": {
"name": "b",
"type": "Identifier",
},
"type": "SpreadElement",
}
]
}
}
]
} |
@mikesherov @ariya could one of you confirm my proposal? |
@markelog Probably not. Much has changed since and master has diverged much vs the old harmony branch. |
Apparently spread element for array initializer has been done by @ikarienator as part of #1045. Thus, let's scope this only for function argument. |
