Basics

// getting the character count
l = thisComp.layer("your text layer").text.sourceText.length;
// getting word count
l = thisComp.layer("your text layer").text.sourceText;
wordsCount = l.split(/ ,| | \./).length;
// parsing number from comp name
myNum = parseInt(thisComp.name.split(" ")[1],10);
// Matching text with regex
thisComp.layer("text").text.sourceText.toLowerCase().match(/\w+\./))

Text repeater

normal
vertical
normal
n = 8; // connect to a slider
s = myText = value ;
for(i=1; i<n; i++) s += myText; s;
vertical
n = 8; // connect to a slider
s = myText = value ;
for(i=1; i<n; i++) s += "\r" + myText; s;

Separating source text line feeds into an array

// Method 1
txt = thisComp.layer("insert Text").text.sourceText;
txt.split("\r")[3]; // Regex
// Method 2:using name as index
txt = thisComp.layer("insert Text").text.sourceText;
myIndex = thisLayer.name;
txt.split("\r")[myIndex]

Numbers

Rounding numbers

to integer
pow
toFixed
to integer
// Use any of the following
Math.floor(value);
Math.ceil(value);
pow
x = time;
pow = Math.pow(10,5) // 5 is the number of decimals
x = Math.round(x*pow)/pow;
toFixed
// apply to sourcetext
x = 2 // number of decimal points
value.toFixed(x);

Counter

startTime = 0
endTime = 2;
startNum = 0;
endNun = 10000
linear(time,startTime,endTime,startNum,endNum);

Binary Generator

n = 300; // connect to slider
seedRandom(seed,true);
let m = b = '';
for(i=0;i<n;i++){
seedRandom(i+seed,true);
b = Math.round(random(1)).toString()
m +=b;
}

Expressions selector

Default

selectorValue * textIndex/textTotal

%

if(textIndex%2) 0 else 100

Random position from textIndex

seedRandom(textIndex,true);
random([100,100]);

Select text indexes explicitly; e.g. 1, 3, 7, 14, 22, etc.?

If you don't have a lot of numbers, then this works:
if(textIndex === 1 || textIndex ===3) {
100;
} else {
0;
}
If you do have a ton of numbers, then this works:
i = [1,3,5,7,10,11];
inArray(i);
function inArray(obj) {
b = 0;
for(i = 0; i < obj.length; i++) {
if(obj[i] === textIndex) {
b = 100;
break;
}
}
return b;
}

Sin wave effector [source]

freq = .5;
selectorValue*Math.sin(time*freq*Math.PI*2 + Math.PI*2* textIndex/textTotal)
