translate javascript to typescript

[Mallegriss]

Hi guys,

I'd like to know how to translate below piece code into typescript:

this.nodes = svg.selectAll(".node")

                        .data(this.forceLayout.nodes()) //<-- get all nodes in data

                        .enter().append("path")

                        .attr("class", "node")

                        .attr("d", function (d) { return d3.svg.symbol()

                                                 .size(d.size); })

I tried this:

.attr("d", (d) => { d3.svg.symbol()

                    .size(d.size)})

it turned out to be below, which doesn't work.

                    .attr("d", function (d) {

                                d3.svg.symbol()

                                    .size(d.size);})

Thanks,

M

sorted out.

 

.attr("d", d3.svg.symbol()

                    .size(d => d.size))

Just wanted to point out that this isn't TypeScript specific, arrow functions are part of ES2015.
