Pass a specified length of array to uniform

Questions
1

Is there any way that I can pass a specified length of array to vertex-shader.
like this:

uniforms = {
  data: {value: [1,2,3,4,5,6, ...]}  // length = 100
}

in vertex-shader :

uniform float data[100]

You can pass such values as defines. Similar to uniforms, you specify defines for a shader material like mentioned in the documentation.

If I define a array like this:

defines: {
  data: [0.0, 1.0, 1.0]
}

then how do I use it in glsl? data[0] ? @Mugen87

Oh , I see… you mean I can pass the length as defines @Mugen87

Have you solved it? There is a similar problem encountered me.And I have no idea how to define the array and use it in shader.

defines: {
	FOO: 15,
	BAR: true
}

# then in glsl: 
uniform float data[FOO]
